------------------
The circumference is 2pi feet.
5 revs will be 10pi feet, or ~ 31.4 feet

For each revolution, the wheel moves a distance equal to the circumference of the circle.
D=2%2Api%2AR
So for 5 revolutions,
D=10%2Api%2AR=10%2Api%2A1=10%2Api or approximately
D=31.4ft

Verify: Use a CD and a ruler. Mark a point on the CD, roll it one revolution until you reach the same point on the CD, then measure the distance traveled using the ruler. It should be about 2%2Api%2AR.
