How to create bounded surfaces from edges ?

I have an extruded cylindrical surface (from a circle sketch). I want to create two other circular surfaces, at the ends of the cylindrical surface.

    it does not seem that there is a tool for creating bounding surfaces per se. What you can always do is to create the surface that you want to close a hole and then trim it to fit using the split part feature. For this example it would work, but i am sure there are a bunch of scenarios where this would be hard to do.

    OK, the revolve method works, very similar to what @shanshan demonstrated, but this is only useful for the cylindrical example you raised.

    I was hoping the more general sweep method would also work, not just for cylindrical cases (which it does, as I imagined it would), but for arbitrary paths like a closed spline (which it appears not to, even if the resultant surface contour makes it non self-intersecting) 

    This appears to be true whether the sweep path is coplanar with the sketch plane for the sweep profile,
    or (as in shanshan's example) on a normal plane, with a pierce relation to the profile.

    Loft with guide curves would work for 4-sided patches, but otherwise I think we need to kludge it with "Split Part" (producing a sacrificial trimming surface which we can then delete) or wait for "Split Face" which hopefully is not far away.

    Am I missing something here? For this case you simply extrude a circle. No?

    My understanding is that the OP (who seems to be missing from the thread) wants a planar surface with circular boundary to cap each end of his cylindrical extruded surface
