\n" ); document.write( "\"x%5E2+%2B+7%5E2+=+11.5%5E2\"
\n" ); document.write( "\"x+=+sqrt%2811.5%5E2+-+7%5E2%29\"
\n" ); document.write( "\"x+=+sqrt%2883.25%29\" or 9.124 (approx)
\n" ); document.write( "The length of the chord is 2x = \"highlight%282sqrt%2883.25%29%29\" cm or approximately 18.248 cm.
