--------------------------
My guess is that you need the negative y points aswell
( y= sqrt{radius^2-x^2} && y= -sqrt{radius^2-x^2} )
to draw both halves of the circle, but if that isn't the problem, maybe
posting a source snippet may be better, cos i'm not to sure from what you
gave what exactly the problem might be.
