Describe the set {(p,o,theta) : p =2 } in spherical coordinates The set is a sphere centered at (0,0,2) with a radius of 2. The set is a cylinder along the z-axis with a radius of 2. The set is a sphere of radius 2 centered at the origin. The set is a plane parallel to the xy-plane that crosses the z-axis at 2.
