x^2 + y^2 + z^2 ≤ 16, 2 ≤ y ≤ 4;

I forgot the rules of inequalitites, I see its an equation of a sphere and the plane is going to be parallel to the xz-plane but i'm lost after that. Any help would be great! thanks!

If you are supposed to find the volume:

The answer is 40pi/3

If you are supposed to find the curved surface area,it is:16pi

If you are supposed to find the total surface area,it is 28pi
