Answer:

6 inches.

Step-by-step explanation:

We have been given that area of a circle is 113.04 cubic inches and we are asked to find the radius of the circle.

We will use area of circle formula to find the radius of our circle.

$\text{Area of circle}=\pi r^2$

Upon substituting the area of given circle we will get,

$113.04=\pi r^2$

Substituting
$\pi=3.14$ we will get,

113.04=3.14*r^2

(113.04)/(3.14)=(3.14*r^2)/(3.14)

36=r^2

Upon taking square root of both sides of our equation we will get,

$r=\pm 6$

Since the radius of the circle can not be negative, therefore, the radius of circle will be 6 inches.
