Evaluate the surface integral II G(x,y,z} dc using a parametric description of the surface. s G[x,y,z) = 222, over the hemisphere x2 + y2 + Z2 =4, 22 0 The value cf the surface integral is E. (Type an exact answer, using :I: as needed.) Integrate g(x,y,z) = x + y + z over the portion of the plane 2x + 2y + z=4 that lies in the first octant. The value of the integral is (Simplify your answer. Type an exact answer.)
