A cone has a radius of 5 inches and a height of 18 inches.

What is the exact volume of the cone?

A.

150π in3

B.

300π in3

C.

450π in3

D.

540π in3

It would be C., because to find the volume, you would have to multiply the radius by itself, to get the diameter. Then, the answer you get will have to be multiplied by the height.: 5 times 5 equals 25, and then 25 times 18 equals 450.
