...MEASUREMENT OF ANGLES. 24. What is the circumference of a circle? The circumference of a circle is a curve line, all the points of which are equally distant from a certain point within, called the centre. Thus, if all the points of the curve AEB are equally distant from the centre C, this curve will be... | |
