Volume of sphere having radius of 3 inches is 113.04 cubic inches.
Solution:
Given that the radius of a sphere is 3 inches. Need to determine the volume of sphere
Formula for volume of sphere is as follows :

Where V is volume of sphere , π is constant value = 3.14 and r = radius of a sphere.
In our case, r = 3 inches
On substituting the value of π as 3.14 and value of r as 3 inches in the formula of volume of sphere, we get

Hence volume of sphere having radius of 3 inches is 113.04 cubic inches.
