How do you calculate the circumference
WebDiameter: the largest distance between any two points on a circle; by this definition, the diameter of the circle will always pass through the center of the circle. It is equal to twice … Webwhile the area of the polygon is A = n T = n a d 4. Hence, we get that A = P d 4 Letting the number of sides n tend to infinity, the polygon "tends" to a circle and we get that Area of the circle = Circumference × diameter 4 or to put it the other way around Circumference = 4 × Area of the circle diameter
