Question

a boiler is in the form of cylinder to meet along with hemispherical ends of 2 metre diameter find the volume of the boiler​

Answer 1

Given height of cylinder (h) = 2m

Diameter of hemisphere (d) = 2m

Radius (r) =1m

vol of cylinder= pi x r^2 x h

vol of 2 hemispheres = 4/3 * pi x r^3

substituting values and ading both volumes we get

v=220/21 cubic metres
