2. (a) Set up an integral in Cartesian coordinates to find the volume of the solid that lies between the xy- plane and the paraboloid z = 25-2-2. (b) Set up an integral in polar coordinates to find the same volume described above. (c) Set up an integral to find the surface area of the part of the paraboloid z = 25-2-y² that lies above the xy-plane. (You choose which coordinate system to use for this.)
