need help with this multivariable calculus problem!

6. Let E be the solid region below the sphere x2 + y2 + z2 = 25, above the ry-plane, and inside the cylinder x2 + y = 9 (sec the diagram to the right). Using either cylindrical or spherical coordinates (one or the other, but not both; you choose which one), set up but do not evaluate an iterated integral that is equivalent to f, 12 dV. Clearly show how you obtained your limits of integration, and circle your final
