Question

The spoke of a wheel reaches from the center of the wheel to its rim. If the circumference of the rim of the wheel is 27 inches, how long is each spoke? Round your answer to the nearest hundredth.

Answer 1

Each spoke is 4.3 inches long.

Since the spoke is from the center of the wheel to its rim, we are looking for the radius of the circle.

Circumference = 2πr
27 = 2(3.14) r
27 = 6.28 r
27/6.28 = 6.28r/6.28
4.30 = r
