    pi r ^2, the radius of a dowel with a 1" diameter is .5".

    3.14 * (0.5)^2 * 12
    or
    3.14 * 0.25 * 12
    or
    3.14 * 3 = 9.42

    9.42 / 1728 = 0.005 in^3

    Re: Dowel rod displacement

    Area of a circle = diameter x diameter x .7854
    1" * 1" * .7854 = .7854
    .7854 * 12 = 9.4248
    9.4248 / 1728 = .0054 ft^3
