You can put this solution on YOUR website!
A = \"pi%2Ar%5E2\" for r
\n" ); document.write( ":
\n" ); document.write( "\"pi%2Ar%5E2\" = A
\n" ); document.write( "\"r%5E2\" = \"A%2Fpi\"; divided both sides by pi
\n" ); document.write( "r = \"sqrt%28A%2Fpi%29\"; find the square root of both sides
\n" ); document.write( "
\n" );
