Question

A beach ball is a sphere with a diameter of 24 inches. Which value is closest to the volume, in cubic inches, of the beach ball? A. 50, b. 101, c. 733, d. 57,906

Answer 1

7234.56.

Explanation:

Given:

Diameter = 24 inches

To find:

Volume of beach ball = ?

Solution:

First of all find radius, r = half of diameter

r =
`(24)/(2) = 12 \ inches`

By using formula,
`Volume \ of \ sphere = (4)/(3) \pi r^(3)`

`Volume\ of \ sphere = (4)/(3) \pi r^(3)`

=
`(4)/(3) *3.14*12*12*12\\(21703.68)/(3) = 7234.56`

Therefore, the correct value of the volume, in cubic inches, of the beach ball is 7234.56.
