  1. To solve this problem, the radius must be in meters and mass in kilograms.

    r = 3 * 10^-3 m
    V = 4/3 * π * (3 * 10^-3)^3 = π * 3.6 * 10^-8
    This is approximately 1.13 * 10^-7 m^3.
    Mass = 0.96 * 0.001 = 9.6 * 10^-4 kg

    Density = 9.6 * 10^-4 ÷ (π * 3.6 * 10^-8)
    The density is approximately 8,488 kg/m^3.
