Question

What is the volume of hemisphere with a radius of 8 ft rounded to the nearest tenth of cubic foot

Answer 1

1072.3
`ft^(3)`

Explanation:

A hemisphere is half of a sphere, so the volume V of the hemisphere is the volume of the sphere divided by 2.

V = (2/3)*
`\pi`
`r^(3)`

= (2/3)*
`\pi`
`(8ft)^(3)`

= (2/3)*
`\pi`*512
`ft^(3)`

= 1072.3
`ft^(3)`
