Located applicable equations at http://en.wikipedia.org/wiki/Circular_segment#Formulas as follows: Area of each segment: A = ((R^2)/2)*(theta - sin(theta)). and Height of each segment: h = R(1-cos(theta)/2) Assuming seven equal segment areas the central angle for topmost chord was calculated as 108.3 degrees, which cannot be correct. Repeatedly reviewed calculations to verify 108.3 degrees but found no arithmetic errors. Need some assistance.
