  1. Given radius of the metallic sphere, r = 4.9 cm

    Volume of the sphere, V = (4/3)r3

    V = (4/3)×(22/7)×4.93

    V = 493.005

    V = 493 cm3 (approx)

    Given Density = 7.8 g per cm3

    Density = Mass/ Volume

    Mass = Density×Volume

    = 7.8×493

    = 3845.4 g

    Hence the mass of the shot put is 3845.4 g.
