Question

7. The cylinder shown has a radius of 3inches. The height is three times the radiusFind the volume of the cylinder. Round yoursolution to the nearest tenth.

Answer 1

250 cubic inches

Step-by-step explanation:

Given that:

Radius of the cylinder, = 3 in.

Height of the cylinder = 3r

= 3(3)

=9 in.

The formula to find the volume of a cylinder is

`V=\pi r^2h`

Plug the given values into the formula.

`\begin{gathered} V=\pi3^29 \\ =81\pi \\ =254.469 \end{gathered}`

Rounding to nearest tenth gives 250 cubic inches, which is the required volume of the cylinder.
