In the table, we see that the relationship between the distance traveled and the number of wheel rotations is a To see why, let’s look at a table showing how far the bike travels when the wheel makes different numbers of rotations. There is an equation relating the number of rotations of the wheel to the distance it has traveled. For example, a bicycle wheel with a diameter of 24 inches has a circumference of 25π inches and will roll 24π inches (or 2π feet) in one complete rotation. This is also how far the circle rolls on flat ground in one rotation. The circumference of a circle is the distance around the circle.
