The cylinder shown has a radius of 3 inches. The height is three times the radius. Find the volume of the cylinder. Round your s

MrRa [10]

Answer:

254.5 Inches Cubed

Step-by-step explanation:

Formula for Finding the Volume of a Cylinder: $V=\pi r^2h$

The radius is 3 inches.

$r=3$

The height is three times the radius.

Multiply the radius by three to get the height.

$h=3*3\\h=9$

The height is 9 inches.

Use the formula to find the volume.

$\pi (3)^29= \pi (9)9=81\pi$

The exact volume is 81 $\pi$ inches cubed.

$81 * \pi$ ≈ 254.47

254.47 ≈ 254.5

The volume of the cylinder should be about 254.5 inches cubed.
