You could use Polar Coords if you really want to.

I could have sworn that there was a way to do this with keys (ctrl, alt, shift). You know, ChOps on-the-fly. But I can't seem to it figure out by dragging from the center. Hmm...

My prefered method:

Drag outside circle.

Save in Alpha Channel.

Go to Alpha Channel.

Drag inside circle.

Fill with black.

Start new Layer.

Load the Alpha.

Fill.
