dear please complete the question so that u can get a good answer

Answer 2

Diameter of the hemisphere is 14cm,
so radius is 7cm.
Total height is 13cm so height of the cylinder is 13-7=6cm.
So the inner surface ares of the vessel is- curved surface area of hemisphere+curved surface area of the cylinder.
2*22/7*7*7+2*22/7*7*6=572cm square.
So the curved surface area is 572cm square.
