The central angle of a circle when you know the radius and arc length, you can use the formula:

Central angle (in radians) = Arc length / Radius

To find the central angle of a circle when you know the radius and arc length, you can use the formula:

Central angle (in radians) = Arc length / Radius

If you want the central angle in degrees, you can convert it using the fact that there are 2π radians in a full circle (360 degrees):

Central angle (in degrees) = (Arc length / Radius) * (180 / π)

Make sure to use consistent units for the arc length and radius, such as meters or centimeters, to obtain accurate results.

Step-by-step explanation:

To determine the man's total monthly salary, we can set up a simple equation using the given information. Let's denote the total monthly salary as "x."

According to the information provided, 33% of the man's monthly salary is equal to Birr 6600. We can express this relationship mathematically as:

0.33x = 6600

To solve for "x," we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.33:

x = 6600 / 0.33

Evaluating the right side of the equation gives:

x ≈ 20,000

Therefore, the man's total monthly salary is approximately Birr 20,000.

Hence, the correct answer is B. 20,000.

The mean of the grouped data is 26.25, the median is 25, and the mode is 20-30.

To find the mean( average) of grouped data, we need to calculate the midpoint of each class interval by adding the lower and upper limits and dividing by 2. Then, we multiply each midpoint by its corresponding frequency and sum up these products. Dividing the total by the sum of the frequencies gives us the mean, which is 26.25 in this case.

To find the median, we first need to determine the cumulative frequency. Starting from the first class interval, we add the frequencies up to each interval to obtain the cumulative frequency. The median falls in the interval where the cumulative frequency exceeds half of the total frequency, which is 15. In this case, it is the 20-30 class interval. We can estimate the median by using the formula: Median = L + ((n/2 - CF) * w), where L is the lower limit of the median class interval, n is the total frequency, CF is the cumulative frequency before the median interval, and w is the width of the interval. Plugging in the values, we find that the median is 25.

The mode represents the most frequent value or interval. In this case, the class interval with the highest frequency is 20-30, with a frequency of 9. Therefore, the mode of the grouped data is 20-30.

Answer:

Step-by-step explanation:

h = 8 cm,  r = 3 cm

A = 2×πr² + 2πr×h = 2πr×(r + h)

A = 2π×3×(3 + 8) =  66π cm² ≈ 207.35 cm²

h = 2×8 = 16 cm ,      r = 3 cm ,   2×66π = 132π cm²

A = 2π×3×(3 + 16) =  114π cm² ≠ 132π cm²  

h = 8 cm ,        r = 2×3 = 6 cm  ,   2×66π = 132π cm²

A = 2π×6×(6 + 8) =  168π cm² ≠ 132π cm²    

Part(A),

The total surface area of the cylinder is 207.35 cm².

Part(B),

The new surface area is about 2.55 times the original surface area, not double.

Part(C),

The new surface area is about 3.64 times the original surface area, not double.

A. To find the surface area of the cylinder, we need to find the area of the two circular bases and the curved lateral surface.

The formula for the area of a circle is A = πr², where r is the radius. So the area of the two circular bases is:

2πr² = 2π(3cm)² = 56.55 cm²

The formula for the lateral surface area of a cylinder is A = 2πrh, where r is the radius and h is the height. So the lateral surface area of the cylinder is:

2πrh = 2π(3cm)(8cm) = 150.8 cm²

Therefore, the total surface area of the cylinder is:

Total Surface Area = 2πr² + 2πrh = 56.55 cm² + 150.8 cm² = 207.35 cm²

B. No, if we double the height of the cylinder while keeping the radius constant, the surface area will not double. The surface area will increase, but not double.

When we double the height, the new height becomes 2 times 8cm = 16cm. Using the formula for the surface area of the cylinder, we get:

New Total Surface Area = 2π(3cm)² + 2π(3cm)(16cm) = 2π(3cm)(28cm) = 528 cm²

The original surface area was 207.35 cm².

The new surface area is 528 cm².

So the new surface area is about 2.55 times the original surface area, not double.

C. No, if we double the radius of the cylinder while keeping the height constant, the surface area will not double. The surface area will increase, but not double.

When we double the radius, the new radius becomes 2 times 3cm = 6cm. Using the formula for the surface area of the cylinder, we get:

New Total Surface Area = 2π(6cm)² + 2π(6cm)(8cm) = 2π(6cm)(20cm) = 753.98 cm²

The original surface area was 207.35 cm².

The new surface area is 753.98 cm².

So the new surface area is about 3.64 times the original surface area, not double.

The radius of the spherical part is 3 inches and the length of the tube is 21 cm.

The capacity of a cylinder, which determines how much material it can hold, is determined by the cylinder's volume. There is a formula for the volume of a cylinder that is used in geometry to determine how much of any quantity, whether liquid or solid, can be immersed in it uniformly.

Given that the volume when the water is fully dipped is 4554 / 7 cm³. The volume when the length is 9 cm empty is 396 cm³.

The two equations can be formed as below:-

4554 / 7 = πr²l + (2/3)πr³

396 = πr²( l - 9 ) + (2/3)πr³

Subtract the second equation from the first,

( 4554 / 7 ) - 396 = 9πr²

9πr² = 254.5

r² = 9

r = 3 cm

The length will be calculated as:-

4554 / 7 = πr²l + (2/3)πr³

4554 / 7 = π( 3 )²l + (2/3)π(3)³

l = 21 cm

Therefore, the tube's length is 21 cm, and the spherical part's radius is 3 inches.

Step-by-step explanation:

The vertical asymptote of the function = ln(x-6) + 5 is option C: x = 6.

The given function is f(x) = ln(x - 6) + 5.

A vertical asymptote is a vertical line that a function approaches but never crosses as it approaches infinity or negative infinity. For a logarithmic function like ln(x), the domain of the function is restricted to positive values only since the natural logarithm is undefined for non-positive arguments.

In the given function, we have f(x) = ln(x - 6) + 5. To find the vertical asymptote, we need to identify the value of x that would make the argument of the natural logarithm equal to zero.

Let's set the argument of the natural logarithm to zero:

x - 6 = 0

Now, solve for x:

x = 6

Thus, the value of x that would make the argument of the natural logarithm zero is x = 6.

So, the correct answer is option C: x = 6.

This means that the vertical asymptote of the function f(x) = ln(x - 6) + 5 is the vertical line x = 6. As x approaches 6 from either side (but never equaling 6), the function's values approach infinity. Similarly, as x approaches negative infinity, the function's values also approach infinity. The function never crosses the vertical line x = 6.

The probability of a core of the two odd number be 1/4.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

The outcome of one die has no bearing on the outcome of the other since the two dice are independent.

In this instance, a complex event's probability is calculated by adding its component simple event probabilities.

Three odd and three even results occur from each roll of the dice. So, the probability of getting an odd number exists \($\frac{3}{6}=\frac{1}{2}$\)

The probability that this happens with both dice exists \($\frac{1}{2} \cdot \frac{1}{2}=\frac{1}{4}$\)

It is relatively simple to list the "excellent" possibilities in this situation because there are a total of 36 outcomes (all numbers from 1 to 6 for one die and the same for the other die). The positive results are

(1, 1), (1, 3), (1, 5)

(3, 1), (3, 3), (3, 5)

(5, 1), (5, 3), (5, 5)

The volume of the composite solid is 4095 cubic yd.

A trapezoidal prism is a three-dimensional object that contains rectangular cross-sections in one direction and trapezium cross-sections in the other. This implies that the prism has two congruent trapezoids that are joined to one another by four rectangles. On the top and bottom of the prism, or bases, are these congruent trapezoids. The trapezium prism's lateral sides are the four rectangles. There are six faces, eight vertices, and 12 edges on a trapezoidal prism.

The volume of the composite solid is the addition of all the solids in the figure.

The volume of the trapezoid prism is:

V1 = (a+b)h(l) / 2

Substituting the values we have:

V1 = (19 + 30)(10)(9) / 2

V1 = 2205 cubic yd.

The volume of the rectangular prism is given as:

V2 = lwh

V2 = 7(30)(9)

P(Odd or Less than 4) = P(Odd) + P(Less than 4) - P(Odd and Less than 4)= 1/10 + 3/52 - 0= 13/130= 1/10, which is the final answer.

The probability that you pick an odd or less than 4 from a card at random can be calculated using the formula for the addition rule of probability that states that the probability of either of two events happening is the sum of their individual probabilities. In this case, the two events are picking an odd card and picking a card less than 4.Picking an odd card:

There are 5 odd cards in a deck of 52 playing cards, namely, Ace of hearts, 3 of hearts, 5 of hearts, 7 of hearts, and 9 of hearts. Thus the probability of picking an odd card from a deck of 52 playing cards is given by:P(Odd) = 5/52 = 5/52Reducing the above fraction to its simplest form by dividing the numerator and denominator by their greatest common factor, we obtain:

P(Odd) = 5/52 = 1/10Picking a card less than 4:There are 3 cards less than 4 in a deck of 52 playing cards, namely, Ace of hearts, 2 of hearts, and 3 of hearts.

Thus the probability of picking a card less than 4 from a deck of 52 playing cards is given by:P(Less than 4) = 3/52Reducing the above fraction to its simplest form by dividing the numerator and denominator by their greatest common factor, we obtain:P(Less than 4) = 3/52

Therefore, the probability of picking either an odd card or a card less than 4 from a deck of 52 playing cards is given by:P(Odd or Less than 4) = P(Odd) + P(Less than 4) - P(Odd and Less than 4)Where P(Odd and Less than 4) is the probability of picking a card that is both odd and less than 4.

Since there are no cards in the deck that satisfy this condition, P(Odd and Less than 4) is equal to 0.

Hence:P(Odd or Less than 4) = P(Odd) + P(Less than 4) - P(Odd and Less than 4)= 1/10 + 3/52 - 0= 13/130= 1/10, which is the final answer.

Ronald Reagan's policies as President of the United States had a significant impact on the country, and opinions about the nature of this impact are often divided.

Some people argue that Reagan's policies had a positive effect on the country, pointing to his efforts to reduce government regulation, lower taxes, and increase defense spending as key factors in driving economic growth. Others, however, see Reagan's policies as having a negative impact on the country, particularly in terms of their impact on social programs, environmental protections, and inequality.
One of Reagan's most notable policy initiatives was his effort to reduce government regulation of the economy. Proponents of this approach argue that reducing government regulation helped to spur innovation and entrepreneurship, driving economic growth and creating jobs. However, critics argue that this approach led to increased pollution, reduced consumer protections, and the prioritization of corporate interests over public well-being.
Another key aspect of Reagan's policies was his focus on lowering taxes. Supporters of this approach argue that lower taxes help to stimulate economic growth and job creation, while opponents argue that they primarily benefit the wealthy and contribute to growing inequality.
Reagan's policies also had a significant impact on social programs, including efforts to cut funding for public education, healthcare, and social services. While some argue that these cuts were necessary to rein in government spending, critics argue that they had a devastating impact on vulnerable populations, exacerbating poverty and inequality.
Overall, opinions about the impact of Reagan's policies on the country are deeply divided, with proponents arguing that his focus on deregulation and lower taxes drove economic growth, while critics argue that his policies contributed to growing inequality and environmental degradation. Ultimately, the long-term impact of Reagan's policies will continue to be debated and studied by economists, historians, and policymakers for years to come.
