Question

In circle P, chord AB is 3 inches from the center and chord CD is 5 inches from the center. Chord CD is ____ than chord AB.

A. longer
B. congruent
C.shorter
D. proportional

Answer 1

The chord that goes through the center of a circle, the diameter, is the longest chord in a circle.  Any other chord will be shorter than this.  The farther a chord is away from the circle, the shorter it will be.  This means that chord CD is shorter than chord AB.
