Question

What is the radius of a circle with an area of 113.04 cubic inches? Use 3.14 for pi. Enter your answer in the box. in.

Answer 1

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,

$113.04=3.14*r^2$  

$\frac{113.04}{3.14}=\frac{3.14*r^2}{3.14}$  

$36=r^2$

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.
