Question

An exercise ball has a radius of 33 cm. In terms of , what is the volume of the exercise ball?

11,979 cm3
35,937 cm3
47,916 cm3
143,748 cm3

Answer 1

Answer:
`47,916\pi \ cm3`

Explanation:

You need to use the formula for calculate the volume of a sphere. This is:

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

Where "r" is the radius.

You know that the radius of the exercise ball is 33 centimeters, then, you must substitute the valueof this radius into the formula
`V=(4)/(3)\pi r^3`.

Therefore, the volume of the exercise ball is:

`V=(4)/(3)\pi (33cm)^3`

`V=47,916\pi \ cm3`
