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( " |
