Ok so I took a GMATPrep test and I was hit with a question that I have no clue how to solve. The questions has a diagram that I couldnt copy and paste but the question reads:

A thin conveyor belt 15 feet long is drawn tightly around two circular wheels each 1 foot in diameter. What is the distance, in feet, between the center of the two wheels?

The answer choices were:

15-pie(3.14)/2
5pie/2
15-2pie
15pie
2pie
