Find an equation of the sphere with center (-3, 2, 5) and radius 4. What is the intersection of this sphere with the yz-plane? Show that the equation represents a sphere, and find its center and radius. 4x2 + 4y? + 422 = 16x - 6y - 12 The solid cylinder that lies on or below the plane z = 8 and on or above the disk in the xy-plane with center the origin and radius 2
