Please do not use CHEGG study website to answer these questions because they are likley wrong:

Evaluate the following surface integrals. 1. Ifs vedS where S is the surface of the sphere a? + y + 2 = 4 above 2 = 1. 2. Ifs (x2 z + y?=)dS where S is the portion of the plane = = 4 + x + yinside the cylinder x2 + y? = 4. 3. f(x, y, =) = x - y where S is given by = = =y' for 0
