Determining diameter from 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 … WebThe following equations show how the radius and diameter relate to the circumference. The equation for circumference of a circle is: c=\pi d c = πd. If written instead in terms of the radius, the circumference calculation is instead: c = 2 \pi r c = 2πr. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia)
