🐞 Description of the bug

length calculation for some arcs is incorrect.

📝 Steps to reproduce

run the attached script which creates an arc for which this bug occurs. Define a line and an arc based on start and end coordinate and a radius (45 units) calculate the line length. calculate the arc length. The arc MUST be longer than the line, because they have the same start and end point. However an incorrect (shorter) arc length is returned by the function. The correct arc length can be calculated from the radius and arc totalangle.
