\n" ); document.write( "the center of a circle is at (-3,2) and its radius is 7. Find the length of the chord, which is bisected at (3, 1).
\n" ); document.write( "~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "The distance between the given points is  \"sqrt%286%5E2%2B1%5E2%29\" = \"sqrt%2837%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is the length of the leg of the right angled triangle, whose hypotenuse is 7.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "THEREFORE, half of the chord's length is  \"sqrt%287%5E2-37%29\" = \"sqrt%2849-37%29\" = \"sqrt%2812%29\" = \"2%2Asqrt%283%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The entire chord is twice this length, or  \"4%2Asqrt%283%29\".    ANSWER\r\n" );
