Hello from MrBillDoesMath!

Answer:

18

Discussion:

Imagine a fixed point on the wheel. The phrase "A bicycle wheel travels 36 pi inches " means that point has traveled 36 pi inches in 1 circumference. As C = 2 Pi r

C = 2 Pi *r = 36 Pi => divide both sides by 2 Pi

r = (36 Pi)\(2 Pi)

r = 18

Thank you,

MrB
