Question

find the distance of chord pq from the centre of circle if diameter pr 50 cm and pq 40 cm​

Answer 1

ANSWER

Assume that circle has center O and chord AB of length 20cm.

ANSWERAssume that circle has center O and chord AB of length 20cm.It is clear that △OAB is an equilateral triangle as all its sides are of the same length. (OA and OB are radii of the circle)

ANSWERAssume that circle has center O and chord AB of length 20cm.It is clear that △OAB is an equilateral triangle as all its sides are of the same length. (OA and OB are radii of the circle)∴∠AOB=60∘ (angle subtended by minor arc at center)

ANSWERAssume that circle has center O and chord AB of length 20cm.It is clear that △OAB is an equilateral triangle as all its sides are of the same length. (OA and OB are radii of the circle)∴∠AOB=60∘ (angle subtended by minor arc at center)∴ length of minor arc(AB)=360∘∠AOB×2πr=61×40π=20.94cm
