Question

The radius of a sphere is 3 inches. Which represents the volume of the sphere?

O 12A cubic inches
O 367 cubic inches
0 647 cubic inches
O 817 cubic inches

Answer 1

The volume is 113.04 cubic inches

Explanation:

We are given:

Radius = r = 3 inches

As we know the formula for finding the volume of sphere is:

`V=(4)/(3) \pi r^(3) \\Putting\ values\ of\ \pi \ and\ r\\V = (4)/(3) * 3.14 * (3)^3\\= (12.56)/(3) * 27\\= (339.12)/(3)\\ =113.04\ cubic\ inches`

The volume is 113.04 cubic inches ..
