    Answer:

    The length of the arc is 10 pi

    Step-by-step explanation:

    Mathematically, the length of an arc is calculated as;

    theta/360 * 2 * pi * r

    theta represents the central angle subtended by the arc which is a right angle according to the question (a right angle is 90 degrees)

    r is the circle radius which is 20 inches

    so we have the length of the arc as;

    90/360 * 2 * pi * 20 = 40 pi/4 = 10 pi
