Let A be the region that in space bounded by the balls:

,

, above the plane

and inside the cone

.

A. Write the integral

in the form:

when :

...

B. Find the volume of A (not necessarily using part A).

Hope you'll be able to help me in this... I think the main problem is that I can't figure out how A looks like... There is also a hint that one of the functions g1 or g2 should be defined at a split region... I can't figure out how this cone looks like and how I can describe A as equations ...

Thanks in advance!
