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 48 inches, how long is each spoke? Use 3.14 for π, and round your answer to the nearest hundredth.
a. 7.64 inches
b. 12 inches
c. 15.29 inches
d. 8 inches

Answer 1

The spoke of a wheel reaches from the center of the wheel to its rim implies that the spoke of the wheel is describes the radius to the wheel. The circumference of a circle is given by C = 2πr. i.e. 48 = 2 x 3.14r = 6.28r => r = 48 / 6.28 = 7.64 inches.Hope this helps. Let me know if you need additional help!
