6. Let E be the solid region that is below parabola z = 3 - x2 - y and above cone z = 2\\x2 + y2. Let the density of the solid at (x, y, z) be p(x, y, z) = 5z. (a). Sketch the solid region E. Label it appropriately. (7 points) (b). Set up iterated integral(s) (DO NOT evaluate) for the mass of E using the rectangular coordinates. (7 points) (c). Repeat (b) using the cylindrical coordinates. (7 points) (d). Repeat (b) using the spherical coordinates. (10 points) (e). Evaluate ONE of the integrals in (b), (c), or (d). (7 points)
