    360 degrees = 2 PI radians

    Central angle = 1.8 PI radians

    Central angle (degrees) = (1.8 / 2) * 360 = 324 degrees

    circle circumference = 26.9 * 2 * PI = 169.0176847631

    arc length = (324 / 360) * 169.0176847631

    arc length =.9 * 169.0176847631

    arc length = 152.1159162868 m
