Problem
An image is supposed to go here. You can help us out by creating one and editing it in. Thanks.

The outside diameter of each of the outer rings is 1 cm less than that of the ring above it. The bottom ring has an outside diameter of 3 cm. What is the distance, in cm, from the top of the top ring to the bottom of the bottom ring?
