Question

What is the volume of a hemisphere with a radius of 39.4 ft, rounded to the nearesttenth of a cubic foot?

Answer 1

Given data

*The given radius is r = 39.4 ft

The expression for the volume of the hemisphere is given as

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

Substitute the values in the above expression as

`\begin{gathered} V=(2)/(3)*3.14*(39.4)^3 \\ =128034.51 \end{gathered}`

Thus, the volume of the hemisphere is V = 128034.51
