A toy is in the form of a cone of radius r cm mounted on a hemisphere of same radius. The total height of the toy is(r+h)cm .then the volume of the toy is

p>Given that,

The radius of toy is r cm and mounted on a hemisphere of same radius.

The total height of the toy is (r+h) cm

Volume of the toy = Volume of cone + Volume of hemisphere

Volume of the toy = 1/3∏r2h + 2/3∏r3

Volume of the toy =1/3∏r2( h + 2r)
