Question

What is the volume of this sphere?

Use ≈ 3.14 and round your answer to the
nearest hundredth.
8 in

Answer 1

2143.57 cubic inches

see notes below regarding radius

Explanation:

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

Your problem doesn't make it clear but I think 8 in is the radius?

So assuming radius = r = 8:

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

vol of a sphere =
`(4)/(3) \pi 8^(3)`

vol of a sphere =
`(4)/(3) \pi 512`

vol of a sphere =
`(4)/(3) \pi 512`

= (682 2/3) * 3.14 = 2143.57333333

So rounded is 2143.57
