how do you find the radius of a circle with a given chord length of 30' and a segment height of 2'? Definition: The chord length is the distance between two points on the circle(AB) and the segment height is measured from the midpoint of chord AB perpendicular to the nearest point on the circle circumference. Thanks

Hello blisstout, I found the formula you need in my "Machinery's Handbook". r = (c^2 + 4h^2) / 8h For your problem: h = 2' c = 30' r = (900 + 16) / 16 = 57.25' Ask for a clarification if this is not what you wanted. Redhoss
