You can put this solution on YOUR website!
Perhaps it's easier than I think but:\r
\n" ); document.write( "\n" ); document.write( "\"A+=+2%28pi%29rx+%2B+%28pi%29r%5E2\"
\n" ); document.write( "\"A+-+%28pi%29r%5E2+=+2%28pi%29rx\"
\n" ); document.write( "
\n" ); document.write( "I'm going to rearrange it here so that x is on the left (personal preference).
\n" ); document.write( "\"2%28pi%29rx+=+A+-+%28pi%29r%5E2\"
\n" ); document.write( "\"x+=+A%2F%282%28pi%29r%29+-+%28pi%29r%5E2%2F%282%28pi%29r%29\"
\n" ); document.write( "\"x+=+A%2F%282%28pi%29r%29+-+r%2F2\"
\n" ); document.write( "
\n" );
