2. Consider a region bounded by x + y + z = 4, z = 0, and x + y = 1. Set up the triple integrals in cylindrical coordinates to evaluate the volume of the region using the following orders of integration: (a) dzdrd (b) drdzd (c) ddzdr. Evaluate the integral for (c). (Answer-5.87) 3. Set up the triple integral in problem (2) using spherical coordinates for dRded.
