You can put this solution on YOUR website!
the distance for the diameter is: \"2%2Asqrt%28%28y-y%29%5E2%2B%28x-x%29%5E2%29\"
\n" ); document.write( "\"2%2Asqrt%28%281%2B7%29%5E2%2B%28-3-5%29%5E2%29\"
\n" ); document.write( "\"2%2Asqrt%28%288%29%5E2%2B%28-8%29%5E2%29\"
\n" ); document.write( "\"2%2Asqrt%28128%29\"
\n" ); document.write( "\"2%2811.3%29\"
\n" ); document.write( "\"22.6\"
\n" ); document.write( "The answer is (A).
