25. Let S be the outward oriented surface which consists of the portion of the radius five sphere x2 + y' + 22 = 25 which lies below the plane z = 3, along with the portion of the plane z = 3 which is within the sphere, so the surface is closed. Let F = (z, y, r) be a vector field. Use the divergence theorem to compute the flux integral J J F . N dS
