Question

A sphere has a radius of 5.3 ft. What is the volume of the sphere to the nearest tenth? use 3.14 for pi.

A) 16.6 ft³
B) 148.9 ft³
C) 522.4 ft³
D) 623.3 ft³

Answer 1

Choice D.) 623.3ft cubed
Hope this helps.

Answer 2

`Volume =623.3ft^3` to the nearest tenth.

Step-by-step explanation

The volume of a sphere is calculated using the formula;

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

where
`r` is the radius of the sphere.

The radius was given as
`5.3ft` in the question.

We now substitute
`r=5.3` and
`\pi=3.14` in to the formula for finding the volume of the sphere to obtain;

`Volume =(4)/(3) (3.14) (5.3)^3`

This implies that;

`Volume =623.3ft^3`
