Chord length =16
\n" ); document.write( "distance from center = 15
\n" ); document.write( "..
\n" ); document.write( "the line from the center to the chord bisects the chord at right angle.
\n" ); document.write( "so half the chord the radius and the line from center to chord form a right triangle.
\n" ); document.write( "radius = hypotenuse
\n" ); document.write( "half thechord = 8
\n" ); document.write( "distance from center = 15
\n" ); document.write( "r^2= 8^2+15^2
\n" ); document.write( "r^2=64+225
\n" ); document.write( "r^2=289
\n" ); document.write( "r= sqrt 289
\n" ); document.write( "r= 17
\n" ); document.write( "
\n" );
