I got a circle, which I know all the details about him. (Radius [100], Diameter [200], Circumference [628.32], Area [31415.93]...)
I would like to surround this circle, with smaller circles. I know the amount of the smaller circles (in this case 14, but it can be less > minimum 4).
I need a formula to calculate the Radius of the smaller circles.
I got the following formula, but this is not right...
R = radius of big circle
n = number of smaller circles
P = tan(360/2n)
r = radius of smaller circles
r = (-(PR))/(P-1)
Here's an example of how it should looks like (this is not right, because I didn't know the Radius of the smaller circles, I just guessed..):
Thank you very much!
