Symbols. C = Circle circumference; π = Pi = 3.14159… r = Circle radius; Radius of Circle. Enter the radius of a … WebCircumference formulas: C = 2πr or C = πd. r is the radius and d is the diameter. The diameter is the longest chord that runs through the center of the circle. The radius is the measure of the distance from the center of the circle to a point on the circle. The diameter is 2 times the measure of the radius. If we want an exact answer, we use π. medication for blood thinning
