WebThe area of any circle is equal to a right-angled triangle in which one of the sides about the right angle is equal to the radius, and the other to the circumference, of the circle. Thus, if we assume that two circles of equal radii have equal area (by Euclid, XII.2), then the two circumferences must be equal. Web**These two formulas are just two different ways of finding the same thing (circumference) because the diameter of a circle $$ =2 \cdot radius $$. So you can use whichever formula …
