Question

The circumference of a circle is 36 pi feet. What is the length of the radius of this circle?

Answer 1

18 feet

Explanation:

Your equation for circumference will always be C = 2πr

In that case, you are given C as 36π

Step 1: Replace known variables

36π = 2πr

Step 2: Divide both sides by 2π

18 = r

And you have your final answer.
