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

Answer 1

The formula for the circumference of a circle of radius r is C = 2pi*r.

Here we know that the circumference is 42 inches, and we need to find the radius, r. Solving this equation for r, we get:

42 inches

r = ------------------ = 6.68 inches, to the nearest hundredth.
