WebThe surface area element is related to the Jacobian (I can't remember exactly how this instant though), so you don't have to calculate the entire cross product. You may also be able to use Gauss's Divergence Theorem, though then you'll probably end up switching to spherical coordinates anyway. 1 comment ( 5 votes) Upvote Downvote Flag more WebTotal surface area of closed hemisphere = 3 πr 2 = 3 × 3. 14 × 10 2 = 942 cm 2. Therefore, the total surface area of given hemisphere is 942 cm 2. Note: A closed hemisphere is also called a solid hemisphere. An open hemisphere is is a hemisphere that is hollow, like a bowl.
