7.) Use spherical coordinates to write the triple iterated integral needed to find the volume of the solid that is bounded below by the half-cone z = E362 + $312 and above by the plane 2 = 1. Do n_ot evaluate the iterated integral. 8.) Use a change of variables to evaluate the given double integral. ff(x + 2y) dA R R: region bound by the parallelogram with vertices (2, 1) , (3 ,0) , (2 ,3) , and (1,4)
