Question

A sports ball has a diameter of 29 cm. Find the volume of the ball. cm 3 Round your answer to the nearest tenth if necessary.

Answer 1

V ≈ 12,770 cm³

Explanation:

a ball is in the shape of a sphere

the volume (V) of a sphere is calculated as

V =
`(4)/(3)` πr³ ( r is the radius )

here diameter = 29 , then r = 29 ÷ 2 = 14.5 , then

V =
`(4)/(3)` π × 14.5³

=
`(4)/(3)` π × 3048.625

=
`(4(3048.625)\pi )/(3)`

≈ 12,770 cm³
