Let D be the region bounded below by the xy-plane, above by the sphere x^2 + y^2 + z^2 = 49, and on the sides by the cylinder x^2 + y^2 = 36. Set up the triple integral in cylindrical coordinates that gives the volume of D using the order of integration dz dr d͵.
Multiple choice:
a) ∫∫∫ r dz dr d͵
b) ∫∫∫ r dz dr d͵
c) ∫∫∫ r dz dr d͵
d) ∫∫∫ r dz dr d͵
