Armin he's right.

Your circle have a 307.8 diameter.

See your screenshot:


And using "dimension->diametric" or "Info->list entities" :


About print preview screenshot:
Print scale 1:1
Circle bounding box 307.8 x 307.8
Paper dimension (A4) 210 x 297

Result: the circle is bigger than the paper

Tip: With "Modify->trim" you can trim a entity or extend it instead of redraw to complete arcs
