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 42 inches, how long is each spoke? Round your answer to the nearest hundredth.

A. 6.69 inches
B. 7 inches
C. 13.38 inches
D. 6.25 inches

C=2*pi*r 42=2*3.14*r 42=6.28*r r=42/6.28 r=6.69 The length of each spoke is 6.69 inches.

42=2*3.14*r

42=6.28*r

r=42/6.28

r=6.69

The length of each spoke is 6.69 inches.
