Hi Charlotte,

Are you drawing a flat disc or a sphere or a cylinder? If it is a disk that is at an anle to the viewer then the shape that you will draw is an 'ellipse' - http://en.wikipedia.org/wiki/Ellipse - which looks a bit like a squashed circle. If it is a sphere the shape will still be drawn circular but the gradation of tone (or 'shading') will give perspective - e.g. http://www.miloduke.com/imgs/cityofgod.JPG - and for a cylinder the round end will be drawn as an ellipse and the long part as two converging lines.

Hope that helps.
