A sphere that has Cartesian equation x 2 + y 2 + z 2 = c 2 x 2 … Webz = x2 +y2 and the plane z = 4, with outward orientation. (a) Find the surface area of S. Note that the surface S consists of a portion of the paraboloid z = x2 +y2 and a portion of the plane z = 4. Solution: Let S1 be the part of the paraboloid z = x2 + y2 that lies below the plane z = 4, and let S2 be the disk x2 +y2 ≤ 4, z = 4. Then darknight relic mystery dungeon
