1. Write inequalities to describe the region: The solid cylinder that lies on or below the plane z=8 and on or above the disk in the xy-plane with a center the origin and radius 2.
I don't understand because I'm using stewart's calculus i have no idea what the equation for a cylinder is? they only show you the eqn of spheres (x-h)^2+(y-k)^2+(z-l)^2 = r^2
