Question

The following sphere has a diameter of 11 inches.

What is the volume of the sphere? Use 3.14 for it and round your answer to the nearest tenth.
O 5,572.5 in.3
O 696.6 in.)
O 174.1 in."
O 126.6 in.3

Answer 1

`\boxed{Volume = 696.9 \ in.^3}`

Explanation:

Diameter = 11 inches

Radius = 11/2 = 5.5 inches

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

Where r = 5.5

V =
`(4)/(3) (3.14)(5.5)^3`

V =
`(4)/(3) (3.14)(166.375)`

V =
`(2090.7)/(3)`

V = 696.9 in.³
