Answer:
A solid toy is in the form of a hemisphere surmounted by a right circular cone. Height of the cone is 2cm and the diameter of the base is 4cm . If ...
Volume of toy = Vol. of cone + Vol.of hemisphere = 13pir^2H + 23pir^3 = 13pir^2 [ H + 2r ] h = 13 × 227 × 2 × 2 [ 2 + 2 × 2 ] = 13 × 227 × 4 .
