in a circle of radius 17cm ,two parallel chords of lenghts 30cm and 16 cm are drawn. Find the distance between the chords, iif both the chords are on the opposite sides of a circentre and onthe same side of the circle

Expert Answer

On opposite side

here , XY is the perpendicular distance

now perpendicular from center will bisect the chord

AX=15

AO = 17...(radius)

apply pythagoras to find 

OX=8cm

similarly in triangle OCY

OY=15 cm

total XY = 23 cm


Now find the distance in case 2 on the same side of the centre

XY = 7cm
