I made the curve into the mesh, then selected the mesh, then press spin and it spins it in 2D and does not make a 3d shape no matter what i change in the sliders. The bottom image is from the side as you can see it is completely flat.
You must set the spin options when you first create the spin, and before you do anything else. By default the center of the spin is at the 3D cursor, but you change that with the Center X,Y,Z boxes.
To make it spin around the right axis fix the Axis settings. X and Y should both be 0, and Z should be 1 or -1. 1 or -1 changes which way the normals will face.
FYI: By default the spin will face the current view. From the front it spins around the Y axis, and looks like a plate. If you set your view to top/bottom before you click spin (and your 3D cursor is at 0,0,0) it will already be in the right orientation.
