A CIRCLE WITHOUT A COMPASS

THE CIRCLE WITHOUT A COMPASSThe sister with the cutting it took to draw a circle the diameter of which more than allows a compass. Rescued… a school ruler, which my dad drilled hole (see figure). The first of them, playing the role axis, is inserted a pin or awl, and the other to the desired distance from the tip of a pencil. Please circle any, up to 30 cm radius.
