Quandaries and Queries 

Can you please help me solve this problem: When Radius=400.00' and Arc=130.58' what is the Cord distance in feet?
Thank you very much. Hi David,
I first drew a diagram, very roughly to scale, and I can see immediately that the answr is just a little less than 130.58"
To describe a solution I need to distort the scale. In the diagram D is the midpoint of the chord AB so angle ADC is a right angle. The length of an arc is given by
