Question

The volume of a right circular cylinder with a base diameter of 8 in. and a height of 6 in. is ___ π in^3.

Answer 1

To calculate the volume of a right cylinder we use the formula:

$V=\pi\cdot r^2\cdot h$

We know the diameter (8in) which is twice the radius (r). Then, the radius of the cylinder is 4in. The height (h) is 6 in. Then, for the volume:

$\begin{gathered} V=\pi\cdot(4in)^2\cdot6in \\ V=16in^2\cdot6in\cdot\pi \\ V=96\pi^{}in^3 \end{gathered}$
