Answer 1

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 :

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

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

`V=(4)/(3) * 3.14 * 3^(3)=4 * 3.14 * 9=113.04 \text { cubic inches }`

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