    1. The problem statement, all variables and given/known data

    2. Relevant equations

    CM = Σmr / Σm
    L = Σ (r x p)

    3. The attempt at a solution

    CM = 0.118 * (0.0036 + 0.00657) / (0.0723 + 0.118)
    = 0.00630614818 m (from the centre of top disk)


    L = Σ (r x p)
    = [0.118 * (0.0036 + 0.00657) / (0.0723 + 0.118)] * 0.0723 * 1.55
    = 0.00070669849

    Check your conversion from centimeters to meters.
