Begin with one
BLACK circle, and inscribe 4 identical, interior, cyclically tangent,
CYAN circles, such that they are also tangent to the black circle.
In each of the four cyan circles, inscribe 4 RED interior circles in exactly the same way.
Finally, inscribe a small GREEN circle in the center of the original black circle, tangent to the cyan circles.
Which is larger, this small green circle, or one of the small red circles?
relation betwen Blue and Black : Rblack= Rblue*rad2, Rred=Rblack/2 , Rgreen=Rred(1-rad2)=Rblack/2=>Rgreen=Rred
