How far does the unicycle move when makes 5 full rotations?

clare says, "the diameter of the unicycle wheel is about 0.5 meters. in 5 complete rotations it will go about 5/2 pi m2."

andre says, "i agree with clare's estimate of the diameter, but that means the unicycle will go about 5/4 pi m."

What is always true when two whole numbers are subtracted?
