Question

What is the radius of a hemisphere with a volume of 49037 ft", to the nearest tenth

of a foot?

Answer 1

28.6 ft

Explanation:

Given an hemisphere of volume
`49037 ft^3`

Volume of a Hemisphere of radius r
`=(2)/(3)\pi r^3`

Therefore:

`(2)/(3)\pi r^3=49037 \\r^3=49037 X (3)/(2 \pi)\\r=\sqrt[3]{49037 X (3)/(2 \pi)} \\r=28.6\: foot`

The radius of the hemisphere is 28.6 foot to the nearest tenth.
