Response Details:
   ===> 
 and      ===>    ===>   
so we have
     ====>      ===>    ====>  and
so the two objects, the paraboloid and the sphere intersect form z = -1 to z = 2
so we have the triple integral
now, when z = 0 is the xy-plane so we have that   for the paraboloid and   for the sphere
so the radius is going from    remember that
also the angle θ varies as follows   
using cylindrical cordinates we have
   the integration is straight forward from there.
Hope this helps
