Question

What is the volume of a sphere with radius of 16 inches?

Use 3.14 for π.


Question 2 options:



17,148.59 in3



200.96 in3



4287.15 in3



1071.79 in3

Answer 1

Hey there :)

We know the volume formula of a sphere is:

`(4)/(3)`
`\pi` (radius)³

We are given the radius = 16 in
And asked to use 3.14 for
`\pi`

Apply the formula
V =
`(4)/(3) (3.14)(16)^3`
=
`(4)/(3) (3.14)(4096)`
= 17,148.58667
≈ 17,148.59 in³

Your answer will be the first option

Answer 2

Volume =

`(4)/(3) \pi {r}^(3) \\ = (4)/(3) * 3.14 * {16}^(3) \\ = 17148.59 \ {in}^(3)`

The answer is the first option.

Hope this helps. - M
