I am trying to create a circular fractal in which each circle is composed by a given number $n$ of smaller circles.
It would look something like this for $n = 8$:
However, I don't know how to calculate the radius of the smaller circles.
Of course I know that the distance from the centre of the bigger circle to the centres of the smaller circles is $r_1 - r_2$, where $r_1$ is the radius of the bigger circle and $r_2$ is the radius of the smaller ones, and that their radius is $\frac{d}{2}$ where $d$ is the distance between two adjacent circles' s centres.
$d$ is for sure related to $n$ but I don't know how to calculate it.
d - r2
in the centre, so it looks more like this. $\endgroup$
