what is the distance between two parallel chords of length 32 cm and 24 cm in a circle of radius 20 cm ?	Choose the correct choice from the following
A) 1 or 7
B) 3 or 21
C) 4 or 28
D) 2 or 14
E) 5 or 14
since the chord length=2sqrrt(r^2-d^2)   chord length=32,r=20 then we get d=12   chord length=24,r=20 then we get d=16   then we add/subtract we get option c) 4 or 28   ANSWER:4 or 28
