If a ten-inch chord of a circle is five inches from the center of a circle, how far is an eight inch chord from the center?
 
draw a segment from the center of the circle perpendicular to the chord ... you should know that this perpendicular segment bisects the chord.

next, draw a radius from the center of the circle to either end of the chord ... what kind of triangle is formed by the radius, the half-chord, and the perpendicular segment? you should know the relationship between the lengths of the three sides.
