Vol.. is

Answer 2

Answer:

Given:

Radius = 1 m

Height = 6 m

Radius of hemisphere = Height of hemisphere = 1 m

Therefore, height of cylinder = 6 - 1 - 1 = 4 m

Volume of container = Volume of cylinder + 2 (Volume of hemisphere)

= πr^2h + 2(2/3 πr^3)

= 22/7 x 1 x 1 x 4 + 2( 2/3 x 22/7 x 1 x 1 x 1)

= 88/7 + 88/21

= 16.76 cubic meter

Total Surface Area of Container = CSA of cylinder + 2( CSA of hemisphere)

= 2πrh + 2(2πr^2)

= 2 x 22/7 x 1 x 4 + 2( 2 x 22/7 x 1 x 1)

= 264/7

= 37.71 square meter
