The chord diameter is a line segment that passes through the center of the circle and connects two points on the circle. The radius is half the length of the diameter. If you have the chord length (C) and the distance from the center to the chord (d), you can find the radius (R) using the formula: R = sqrt((C/2)^2 + d^2).
