What is the exact volume of the cylinder?

A.) 18π in3

B.) 36π in3

C.) 54π in3

D.) 63π in3

The volume of the cylinder is based on the formula: Volume = base * height where base is the circular shapebase area is equal to pi r^2. radius in this case is 3 inches and height is 6 inches. Hence the volume is pi * 3^2 * 6 or equal to 54 pi. The answer to this problem is C. 54 pi in3.
