To use a protractor by Jason Lazar.

A protractor is held in the hand you do not write with. The protractor has a point on one end of an arm and a lead on the other one. Hold the protractor and place the point where you want the center to be. Adjust the free arm to the desired circumference, then take your free hand and hold the top protractor and swivel as the arm with the lead is on the surface creating an arc.
