Let E be the region in the first octant of R that lies inside the sphere x + y +2= 4 and above the cone z = x + y. (a) Set up (but do not evaluate) iterated integrals that compute the volume of E... (i) ...in Cartesian coordinates, with order of integration dx dy dz. (ii) ...in cylindrical coordinates, with order of integration dz dr do. (iii) ...in spherical coordinates, with order of integration dp do de. Be sure to provide some justification for your answers. (b) Evaluate one of your integrals from part (a). [To check your work, you may want to evaluate them all. But only submit one evaluation. The TAs will only grade one.]
