<h2>Answer:</h2>

C = 2πr

r = C/2π ...(1)

A = πr²

A = π(C/2π)² = πC²/4π²

A = C²/4π.

<u>Correct choice</u> - [A] A = C²/4π.

Big Ben (the clocktower) in London has a circumference of 72.22 feet and an area of 415.27 feet^2. What is the diameter AND radi
Mashutka [201]

Answer:

Diameter = 23  Radius = 11.5

Step-by-step explanation:

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

<em>72.22 ÷ 3.24 = 23</em>

diameter = 23

Divide the diameter by 2.

<em>23 ÷ 2 = 11.5</em>

There you go, you found the circle's radius

5. Give two equations that will cross at (3, 4)
Anton [14]

Answer: 4x=3y, 8x=6y

Step-by-step explanation: We can use a simplified form of an equation for this specific problem, since a solution is (3,4), if you plugin 3 for x and 4 for y you get the same thing. Since 4 times 3 equals 3 times 4 you can call x as 4 and y as 3. You can simply multiply this by 2 for another equation since it doesn't affect the ratio. I hope this helps!

Please put the correct answer thank you :)
MatroZZZ [7]

Answer:

The answer to your question is: letter D

Step-by-step explanation:

Data

f(x) = x³ - 9x

g(x) = x² - 2x - 3

Process

               \frac{x^{3}- 9x }{x^{2} - 2x - 3}

Factor both numerator and denominator

    \frac{x(x^{2}-9) }{x^{2} - 2x - 3} = \frac{x(x + 3)(x-3)}{(x - 3)(x + 1)}

Simplification

                          \frac{x(x + 3)}{(x + 1)}

EF is a median of trapezoid ABCD. what is the value of x?
goldfiish [28.3K]
Since the given figure is a trapezoid, here is how we are going to find for the value of x. Firstly, the sum of the bases of the trapezoid is always equal to twice of the median. So it would look like this. 2M = A + B.
Plug in the given values above.
2M = (<span>3x+1) + (7x+1)
2(10) = 10x + 2
20 = 10x + 2
20 - 2 = 10x
18 = 10x < divide both sides by 10 and we get,
1.8 = x
Therefore, the value of x in the given trapezoid is 1.8. Hope this is the answer that you are looking for.
