Question

Let g be the solid slab bounded by the sphere x^2+y^2+z^2=4 and two planes z=0 and z=1. The volume G is given by the triple integral with integrand 1dV. Set up integrated integrals for this triple integral in terms of (a)cylindrical coordinates, (b)spherical coordinates

[hint both (a) and (b) involve two iterated integrals] draw a picture please
