Variable radius of curvature in terms of sagitta

How can I express a radius of an arc R in terms of its sagitta H assuming that: (a) the arc follows a locus of a circle with a variable radius, (b) arc length S is constant. I’m interested in the region where the included angle of the arc is between but not equal to 0° and 4°.

I don't know what "circle with variable radius" means. Are you talking about a general curve with variable radius of curvature?
Thanks from topsquark
