the spoke of wheel reaches from the center of the wheel to its rim. If the circumference of the wheel is 42 inches, how long is each spoke? Use 3.14 for pi, and round your answer to the nearest hundredth

Respuesta :

If each spoke reaches from the center of the wheel to its rim, then that means that each spoke is as long as the radius.

To calculate radius:

C=2πr

π=3.14
C=42 inches

42=2(3.14)r
2*3.14=6.28
42=6.28r

Divide 42 by 6.28

42/6.28=6.68

length of each spoke is 6.68 inches.
