  • Re-do calculation of density of bowling ball done earlier paying more attention to accurate measurement of diameter, and correct precision of measurements and calculated results.

    Measure diameter precisely with large caliper (or bar on ring stand lowered to top of ball).

    Care with propagation of errors gives:

    D = 5.44 x 103 g / 5.58 x 103 cm3 = 0.974910394 g/cm3
