Question

The volume of the sphere is ____ π cubic feet.

Answer 1

Step 1

Write the expression for the volume of a sphere

`V\text{ = }(4)/(3)\pi r^3`

Where r = 21ft

Step 2

Substitute in the values and find the volume.

`\begin{gathered} V\text{ = }(4)/(3)*\pi*21^3 \\ V=\text{ }21,348\pi ft^3 \end{gathered}`

Hence the volume of the sphere = 21,348πft³
