Question

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

Answer 1

Answer: The answer is 18 or eight-teen

Answer 2

Answer: 18 feet

Step-by-step explanation:

Given: The circumference of circle is given by :-

$\text{Circumference}=2\pi r$, where r is the radius of the circle.

Since, The circumference of a circle$=36\pi$ feet.

$2\pi r=36\pi\\\\\Rightarrow\ r=\frac{36\pi}{2\pi}i\\\\\Rightarrow\ r=18\text{ feet}$

Hence, the radius of the circle = 18 feet.
