The volume of a cylinder is given by:



Just put in the numbers for r and h and then do the arithmetic.

By the way, rounding your answers to the nearest hundredth is utterly inappropriate in both of these problems. The results of calculations based on measurements should never be expressed to a precision greater than the least precise given measurement. Problem a) should be expressed to the nearest centimeter, and problem b) to the nearest meter. And using 3.14 for is plenty close enough here. That's not to say you shouldn't follow instructions, it's just that IMHO, the instructions are wrong.
