# Sketching circles, Edexcel. watch

1. Hey, I was wondering how circles are to be sketched. Can a compass be used and they be drawn or do they need to be done freehand? This is with regard to questions in FP2 and C2. I am unaware and need to know. Thanks in advance.
2. Sketches are normally done freehand and just show and intersections with axis and such. I imagine in a circle you would need to show the centre, and then the radius.

Oh allright, I was hoping I wouldn't have to waste so much time drawing wonky circles
4. I mark the diagram proper, putting in the equation, whether it be in cartesian form or not,the origin as always, the centre of the cirlce and EVERYTHING else. Will that be enough or does it have to be a perfectly round circle?
