The height of a can is 3 times its radius. If the radius of the can is 3 centimeters, what is the volume?

Semmy [17]

Answer:

170 $cent.^{3}$

Step-by-step explanation:

If the height is 3 times the radius you can find that by: 3r

r = 3.

So: 3 x 3 = 9

The height is 9 centimeters

Volume of a cylinder (can):

$V= 2\pi rh$

Plug in what we know

$V = 2 \pi (3) (9)\\V = 54\pi \\V = 169.646\\$

Rounds to: 170
