Question

a circle has 2 parallel chords at a distance of 5cm from the centre of circle find the length of chord in terms of radius​

Answer 1

Step-by-step explanation:

so frist you have draw one circle with two radius and name it as M, N, P, B, tita

next,MN =6cm PQ=8cm radius =ON=OQ=5cm

AN =6/2=3[bcoz the perpendicular drawn from the centre to the chord bisetcs the chord

by Pythagoras therom

5 square =OA square +3 square

so we will get OA = 4cm ..

like that,triangle OBQ OQ =4cm ,OB=3cm

• now AB +AO+ OB =4+3=7cm..
