Hello.
I have a picture here:

I have one dot already placed, and I need to place other dots on
the circle and know their coordinates.

I know the lenght of circle ©, radius®, number of dots needed
and the distance between points. I must place them all
in circle. Please notice that sizes C,r,distance may change.
I need a formula to find the coordinates of every point.
I have made a better drawing:
P.S. Coordinates can be a rational number (5.6,10.8 etc.)
Thanks for any help.
