I could really use some help with this problem because I'm pretty confused on what to do.

The formula for the volume of a cone is V=1/3(pi)r^2h where v represents volume, r represents the radius of the base, and h represents the height. What is the height of a cone with a volume of 66 cubic centimeters and a base with a radius of 3 centimeters?

Square r.

66 = 1/3(3.14) 9 h

Combine terms.

66 = 3 * 3.14h = 9.42h

Divide both sides by 9.42.

7 = h
