the fibre curves by 4mm up here

a __________________ b (200mm)

with 4mm offset in the centre of the line, making the length greater than 200mm, but I don't know what that length is. I would also like to know what the radius of a circle with 4mm of circle curvature at the perimeter separated by 200mm is?
