(1 point) Let er be the unit radial vector and r = Vx2 + 92 + z2. Calculate the integral of F = e Te, over: (a) The upper-hemisphere of a + y2 + 22 = 36, outward-pointing normal (b) The region on the sphere of radius r = 3 centered at the origin that lies inside the first octant x, y, z 2 0 (a) SSS F . dS = 72pi*e^(-6) (b) SSS F . dS = 4.5pie(-6)
