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