  1. Given radius of metallic cones, r = 2 cm

    Height of cone, h = 3 cm

    Volume of cone = (1/3)r2h

    = (1/3)×22×3

    = 4 cm3

    Radius of the solid sphere, R = 6 cm

    Volume of the solid sphere = (4/3)R3

    = (4/3)63

    = 4××2×6×6

    = 288 cm3

    Number of cones made from sphere = Volume of solid sphere / volume of the cone

    288/4

    = 72

    Hence the number of cones that can be made is 72.
