What is the length of a spoke of a wheel if the circumference of the rim is 48 inches?

The length of a spoke of a wheel is not directly determined by the circumference of the rim. The spoke length typically depends on the wheel's design, including the hub size and the depth of the rim. However, if we assume a basic scenario where the wheel is a perfect circle, the length of the spoke would be the radius. Given the circumference (C) is 48 inches, you can find the radius (r) using the formula ( C = 2\pi r ). This gives ( r = \frac{C}{2\pi} \approx \frac{48}{6.28} \approx 7.64 ) inches.
