**Homework Statement**

The outermost integral is:

-2 to 2, dx

The middle integral is:

-sqrt(4-x^2) to sqrt(4-x^2), dy

The inner most integral is:

x^+y^2 to 4, dz

**The attempt at a solution**

Drawing the dydx in a simple 2d (xy) plane, it is circular with a radius of 2. So this means that the period(theta) will go from 0 to 2pi. Drawing in 3d (xyz) yields a hemisphere/paraboloid. Now this is where I'm stuck. I don't know what to do after this or how to really tackle this problem. Do I want to attempt to draw a 'slice' of it in the spherical outline with the variables phi, rho, theta? Do I have to look at it a certain way (2d or 3d)? I just don't see what I can do!

Any help or guidance is greatly appreciated!!
