please answer the projection question.
There was calculation mistake. Answer is 41.09
here we have to find surface area of sphere under cylinder part . So we have taken projection of cylinder .
isn't the projection = the intersection of the surfaces?
it depends on kind of question , here no need to take projection .
always go through language of question for such type of question . There is no fixed way to solve such question .
