    20 Pi feet or 62.8318530718 ft

    Step-by-step explanation:

    Find the circumference

    Pi X diameter

    radius = 1/2 diameter

    radius * 2 = 20

    10π feet, or about 31.42 feet

    Step-by-step explanation:

    Diameter = 2 times radius, so the radius is 5 feet.

    The question is asking us for the circumference - the distance around the circle. Plug our radius into the formula.

    C = 2πr

    C = 2π (5)

    C = 10π feet = about 31.42 feet
