that lower part is supposed to be a hemisphere

Answer 7

whats the problem after you have the correct figure ?
inner surface area = surface area of cylinder + that of hemisphere.

The hemisphere has a radius of 7 cm, so that leaves the height of the cylinder as 13 cm - 7 cm = 6 cm. You know how to find surface area of a cylinder and hemisphere, right?
