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(A-B) 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.
