The line from the center of the circle
\n" ); document.write( "is perpendicular to the chord and meets
\n" ); document.write( "at it's center. A right triangle is formed
\n" ); document.write( "by this line and 1/2 of the chord. The line
\n" ); document.write( "from the center to where the chord meets the circle
\n" ); document.write( "is the radius, which measures:
\n" ); document.write( " $\"sqrt%284%5E2+%2B+3%5E2%29\"$
\n" ); document.write( " $\"sqrt%2816+%2B+9%29\"$
\n" ); document.write( " $\"sqrt%2825%29\"$
\n" ); document.write( " $\"5\"$
\n" ); document.write( "The radius is 5 cm long \n" ); document.write( "

\n" );
