the side of the square =diameter of the circle or 2*radius
==
area of circle = 308=pi%2Ar%5E2 therefore r=Sqrt%28308%2Fpi%29=9.8 I am using pi=3.142
==
side of square =2%2Ar=19.6
==
diagonal of a square (forming a 90-45-45 triangle, the diagonal is the hypothenus=sqrt%282%29%2Aside=sqrt%282%29%2A19.6=27.7
