I need to get point on the circle by specified length. For example, there is a circle with radius=1.5 and circumference=9.42. And if I set length=4.71 (half of the circumference), then I should get point on the 180 degrees.
I think I need to convert the length to the radians, but I don't understend how to do that.
.
Currently, it calculates length as radian, but thats wrong.
