Suppose you have a circle that is 1 cm in radius. Now you add many more.

How do you align these so that you can create a big ring made up of these circles?

how do you calculate where the second circle should be placed, the third one, etc.?

I will use this platform to test the answer.

I have a 5 pixel radius dot in a 200x200px platform. Lets assume this dot represents the top of the
ring that is to be created.

Where should the next dot be placed? And all the other dots so that I can create a perfect ring with these dots?
