The diameter of one bicycle wheel is 28 inches and its spokes run from the hub (or center) to the edge of the rim. The diameter of another bicycle wheel 21 inches. What is the difference in inches between the length of the spokes of the two wheels?

This one is fairly straight-forward
The radius of each of the wheels are 14 inches and 10.5 inches.
Therefore, the difference in inches between the length of the spokes of the two wheels is 3.5 inches.
