This region in the first octant is bounded by the coordinate planes and the paraboloid x^2+y^2+z=4. If the volume of the region is given by the double integral

intgral from 0 to 2 integral from 0 to B (A dydx)

What is A?

What is B?

I dont know how to solve this problem.

*I attached a word doc with the integral because I dont know how to properly show integrals in forum. *

Thanks
