Question

A vessel is a hollow cylinder fitted with a hemispherical bottom of the same base. The depth of cylinder is 14/3m and internal surface area of the solid?

Answer 1

Given radius of hemisphere (r) = 3.5/2 = 1.75m

Height of cylinder (h) = 14/3m

Internal surface area of solid ( *)

• = Surface area of cylinder + surface are of hemisphere

Internal surface area of solid ( *) = 70.51m3
