# A tent is cylindrical in shape with a conical top above it. The radius of the base of the tent is 7m. The height of the cylindrical part is 20 m and the height of the conical part is 4 m. Find the volume of air in the tent.

Answer :

Volume of cylindrical part = π r

= × 7 × 7 × 20 m

= 3080 m

Volume of conical part =π r

= x x 7 x 7 x 4m

.

= (3080 + 205.3) m

= 3285.3 m

^{2}h= × 7 × 7 × 20 m

^{3}= 3080 m

^{3 }Volume of conical part =π r

^{2}h= x x 7 x 7 x 4m

^{3}^{ }= 205.3 m^{3 }.

^{.}.Volume of air in tent = volume of cylindrical part + volume of conical part= (3080 + 205.3) m

^{3}= 3285.3 m
