1. The problem statement, all variables and given/known data Find the volume of a region bounded above by the unit sphere x^2+y^2+z^2=1 and below by the cone z=sqrt(x^2+y^2). I am really confuse here.. >< 2. Relevant equations Sphere: x^2+y^2+z^2=1 Cone: z=sqrt(x^2+y^2) 3. The attempt at a solution I had plot the graph of the sphere and cone and i am pretty confuse to use. Just want to have some help.
