Answer:

The answer is option C

Explanation:

Circumference of a circle = 2πr

where

r is the radius of the circle

From the question

Circumference = 36π inches

To find the radius substitute the value of the circumference into the above formula and solve for the radius

That's


36\pi = 2\pi r

Divide both sides by 2π

We have


(36\pi)/(2\pi) = (2\pi \: r)/(2\pi)

We have the final answer as

r = 18 inches

Hope this helps you
