How do I evenly distribute a random amount of points on the circumference of a circle given only the radius?

Question

The center of the circle being (0,0) and the first point being (0,r) if I wanted to clockwise plot these points along the circumference of the circle with identical arcs, what would be the equation?

It's a random amount of points but for the equation we will say there are 9 points. For brevity sake.

Answer 1

Draw and label a diagram!

r = radius of circle

2πr = circumference

For 9 points each should be spaced 2πr / 9.
