Answer:

Explanation:

The volume of an sphere is defined as

$V=(4)/(3)\pi r^(3)$

According to the problem, the volume of an sphere is 113.04 cubic inches. If we use this fact, we can find the radius

$113.04=(4)/(3)\pi r^(3)$

$113.04=(4)/(3)\pi r^(3)\\(3(113.04))/(4\pi)=r^(3) \\r=\sqrt[3]{27}\\r=3$

Therefore, the radius is 3 inches long.
