Question:

A silo consists of a right circular cylinder of diameter 4 m. and altitude 6 m.?

It was surmounted by a right circular cone of the same diameter and altitude 3 m. Find the total volume of the silo.

Answer:

The volume of a cylinder is given by the formula: V(cylinder) = pi r? h r = 4, h = 6 Hint: 96 pi :-D The volume of a cone is given by the formula: V(cone) = 1/3 pi r? h r = 4, h = 3 Hint: 1/3 * 48 pi = ? I can plug in the numbers, but you can solve it just as easily. Hint: A multiple of pi that has three digits. Two are 1 and one is 2. :-)
