Explanation
The volume of the cylinder is given as;
[tex]V=\pi r^2h[/tex]
Recall that the radius of the cylinder is given as 3 inches while the height of the cylinder is three times the radius.
[tex]\text{Height}=\text{ 3}\times radius=3\times3=9inches[/tex]
Therefore, the volume of the cylinder becomes;
[tex]V=\pi\times3\times3\times9=81\pi=254.47\text{ cubic inches}[/tex]
Answer: 254.5 cubic inches
