    The length of an arc is the fraction of its circumference based on the given intercepted angle. This is given by the equation,

    L (arc) = (Angle / 360) x 2πr

    Substituting the known values,

    L (arc) = (40 / 360) x 2π (8 inch) = 16π/9 inch

    Thus, the length of the arc is approximately equal to 5.585 inches.
