    Length of Arc = 4

    Step-by-step explanation:

    Circumference is the whole circle's perimeter.

    Arc length is a "part" of the circumference.

    Whole circle is 360 degrees, so the arc length with a central angle of 72 degrees will be:

    72/360 = 1/5th of the whole circle

    The whole circle has circumference of "20", so 1/5 th of that would be:

    (1/5) * 20 = 4

    Length of Arc = 4
