Question

Christine fills a ball in the shape of a sphere with air .The diameter of the ball when it is filled is 18 inches.How much air in cubic inches is in the ball when it is filled

Answer 1

`V=3052.08\ in^3`

Explanation:

Given that,

The diameter of the ball, d = 18 inches

Radius, r = 9 inches

We need to find the air in cubic inches is in the ball when it is filled. The volume of a sphere is given by :

`V=(4)/(3)\pi r^3\\\\=(4)/(3)* 3.14* (9)^3\\\\=3052.08\ in^3`

So,
`3052.08\ in^3` of air is in the ball.
