Please review the solutions to the previous week's set. Then, move onto this one. In the meantime, be looking at the marathon problems.

2. Two congruent cones with radius 12cm and height 12cm are enclosed within a cylinder. The base of each cone is a base of the cylinder, and the height of the cylinder is 24cm. What is the number of cubic centimeters in the volume of the cylinder not occupied by the cones? Express your answer in terms of π.
3. The sum of three different prime numbers is 40. Find the product of the largest two of the primes.

5. A positive three digit integer is divided by a positive two digit integer, yielding an integer quotient and zero remainder. What is the smallest possible integer quotient?
