# Find the total vo

Given.

Radius of cone and hemisphere = 21 cm

Total height of cone = 60 cm

Formula used/Theory.

Volume of Cone = πr2h

Volume of hemisphere = πr3

As we put Cone on hemisphere

The circle part of both cone and hemisphere will attach

Volume of solid is sum of volume of both cone and hemisphere

Volume of solid = Volume of cone + Volume of Hemisphere

= πr2h + πr3

= πr2[h + 2r]

As height of hemisphere is equal to radius of hemisphere

Then;

Volume of top = × 21 × 21 × [60 + 2 × 21]

= × 21 × 21 × [60 + 42]

= × 21 × 21 × 

= 22 × 21 × 102

= 47124 cm3
