A tire is 22 inches in diameter and rests on a platform that is 4 inches above the ground.

The six o'clock position on the tire is level with the platform. A piece of gum stuck to the three
o'clock position of the tire completes 1 full revolution in 12 seconds. The function h(t) gives
the height of the piece of gum in inches above the ground t seconds after the tire begins to
turn. Find a formula for the height function h(t).

Did your professor perhaps want to do handle it as a sinusoidal case?

Here is a page you might want to look at that fits your problem:
