is it a dependence between d ( diagonal of square from equal of area of circle ) to r ( ray of this circle ) d / r

pi * r ^ 2, pi * sqrt(2) ^ 2, d = sqrt(2) * d ( for third value ) ....

based on ricle r = 1, course is side of square around of circle, and diagonal from eaual of area of circle, this three values are course of next circle rays

and 2 r / sqrt ( 2 ) = sqrt ( 2 ) for r = 1
