Can't be done.  It's the wrong command.

It's odd that while you were looking at Circle in the online help, perhaps
after typing it in the index, you didn't notice the entry "See also: Disk"
with a hyperlink.  

Try

	Show[Graphics[Disk[{2, 0}, 1]]];

Then try it with 

	Show[Graphics[Disk[{2, 0}, 1]], AspectRatio -> 1];

To get something that looks like a filled in circle.

Regards,

Dave.
