1. The problem statement, all variables and given/known data

Hi there. Well, I have the next exercise, which I've solved, but I don't know if the solution I got is the right one.

It says Given the next region on spheric coordinates find the expression for it in rectangular coordinates, and plot.

Well, In think it is a part of a cone, without a sphere of radius 1, with a sphere of radius 2 on the top.

2. Relevant equations

3. The attempt at a solution

Is this right?
