You can put this solution on YOUR website!
The key to understanding the solution is recognize that a diagonal of the square is a diameter of the circle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"pi%2Ar%5E2=A\", and you know A.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Letting d be diameter,
\n" ); document.write( "\"pi%2A%28d%2F2%29%5E2=A\"
\n" ); document.write( "\"highlight_green%28d%5E2=4A%2Fpi%29\"
\n" ); document.write( "\"d=2sqrt%28A%2Fpi%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Another key to solving is recognize the square is two 45-45-90 special right triangles, and you can use Pythagorean Theorem formula.
\n" ); document.write( "Let x be a side of the square.
\n" ); document.write( "\"2x%5E2=d%5E2\"
\n" ); document.write( "and you can solve this for x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This solution almost but not finished, was done purely in symbols, and you can finish.
