  1. (i)Given radius, r = 6 cm

    Height, h = 7 cm

    Volume of the cone = (1/3)r2h

    =(1/3)×(22/7)×62×7

    = 22×12

    = 264 cm3

    Hence the volume of the cone is 264 cm3.

    (ii) Given radius, r = 3.5 cm

    Height, h = 12 cm

    Volume of the cone = (1/3)r2h

    =(1/3)×(22/7)×3.52×12

    = (22/7)×12.25×4

    = 154 cm3

    Hence the volume of the cone is 154 cm3.
