A revolution is one turn of a wheel or once round a circle.

The distance that a point on the perimeter of a circle or a wheel travels during one revolution is the length of the circumference (C). This is given by the formula C = 2πr, where r is the radius.

If the radius is measured in feet, then the length of the circumference will be in feet. If the radius is measured in a different unit of length then the answer will need converting from that unit into feet.
