What is the distance in cm between two parallel chords of lengths 32 cm and 24 cm in a circle of radius 20 cm

Options are:
1)1or7 2) 3or21 3)2 or 14 4)4 or 28

• 28,4
  length from center to the chord 1= sqrt(20^2-16^)=12
  similarly length from center to chord 2= 16
  distance b/w them=16+12 or 16-12

• Draw diagram and
  recognize two right-angled triangles,
  By applying Pythagoras theorem,
  20^2=12^2+x^2 and
  20^2=16^2+y^2,
  On solving,
  x=16, y=12
  Thus answer will be
  x+y=28 and x-y=4
