    502.40 inches

    Step-by-step explanation:

    First we need to find the circumference of the wheel, which is given by pi times the diameter:

    C = (3.14) (20) = 62.8 inches

    That's how far the unicycle will travel in 1 revolution, so from there just multiply by 8

    D = (62.8) (8) = 502.40 inches
