    20.94 inches

    Step-by-step explanation:

    Mathematically, length of an arc = Theta/360 * 2pi * r

    According to this question, theta is 2 pi/3 and r is 10 inches

    Kindly note that 2pi/3 radians = 120 degrees

    Substituting these values, we have;

    120/360 * 2 * pi * 10

    20pi/3 = 20.94 inches
