Question

Two parallel chords of lengths 30 cm and 16cm are drawn on the opposite sides of the centre of a circle of radius 17 cm. Find the distance between the chords

Answer 1

hope it will help you

Answer 2

Answer:23cm

Step-by-step explanation:     consider triangle POA

OA=17cm, PA=AB/2=15cm

OA^2-PA^2=PO^2

17^2-15^2=PO^2

289-225=PO^2

64=PO^2

8cm=PO

NOW CONSIDER TRIANGLE DOS

DS=CD/2=8CM, OD=17CM

DO^2-DS^2=OS^2

17^2-8^2=OS^2

225=OS^2

15CM=OS

DISTANCE BETWEEN THE CHORDS = OS+PO

=15+8=23CM
