if the radius of the small circle is 0.1km, how big is the radius

>>8224624

That's not even a circle

>>8224700
y-yes it is?
the green almost-hexagon fits inside the red circle exactly, im looking for the ratio of the big/red circle to the small/black circle, with respect to the number of circles in the radius of the big/red circle

i assume something in the form R=x+ar

[math] \dfrac {r_i}{r_u} = \dfrac { \sqrt{3} } {2} = 0.866 [/math]

[math] R = (1+2+2+1) \cdot r_i + 1 \cdot r_u = \left( 6 \cdot \dfrac {r_i}{r_u} + 1 \right) r_u = 6.196 \cdot r_u [/math]

7 small circles go across the diameter of the large circle

>>8224624
so where in Germany do you live?

>>8224756
no they don't, because they're not edge to edge, they overlap
>>8224758
near sheffield, UK

>>8224759
alright, okay. had to be something classically European like Germany, France, UK or Austria judging by the fucked up fields. centuries of heritage..

>>8224751
so what would this be for a hexagon of n circles per side, say?

>>8224624

0.622 km

>>8224768
