Question

Find the volume of the sphere. Give the answer in terms of pie and rounded to the nearest cubic foot.

Answer 1

We have to calculate the volume of a sphere with radius r = 3 ft.

We can calculate the volume using the following formula:

$\begin{gathered} V=\frac{4}{3}\pi r^3 \\ V=\frac{4}{3}\pi\cdot3^3 \\ V=\frac{4}{3}\pi\cdot27 \\ V=\frac{4\cdot27}{3}\pi \\ V=36\pi \\ V\approx113 \end{gathered}$

Answer:

The volume is 36π ft³ or approximately 113 ft³.
