  1. (i) Radius of sphere, r = 7 cm

    Using, Volume of sphere = (4/3) πr3

    = (4/3)×(22/7)×73

    = 4312/3

    Hence, volume of the sphere is 4312/3 cm3

    (ii) Radius of sphere, r = 0.63 m

    Using, volume of sphere = (4/3) πr3

    = (4/3)×(22/7)×0.633

    = 1.0478

    Hence, volume of the sphere is 1.05 m3 (approx).
