Question

Val measures the diameter of a ball as 12 inches. How many cubic inches of air does this ball hold

Answer 1

This ball holds 904.78 cubic inches of air.

Explanation:

Volume of the ball:

A ball has a spherical format. The volume of a sphere is given by:

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

In which r is the radius, which is half the diameter.

Val measures the diameter of a ball as 12 inches.

This means that
`d = (12)/(2) = 6`

How many cubic inches of air does this ball hold?

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

`V = (4\pi*6^3)/(3)`

`V = 904.78`

This ball holds 904.78 cubic inches of air.
