Question

Distance between two parallel chords when radius is given

Answer 1

let the radius of the circle whose parallel chords are Ab and cd be r

hence,
radius=r
chords are Ab and CD
therefore the distance of the chords from centre is given by= √(r²-ab²/4)

similarly the distance of the chord cd from the centre is given by=√(r²-cd²/4)

thus the distance between the chord when they are in different semicircle is given by =√(r²-ab²/4)+√(r²-cd²/4)

when they are in same circle then the distance=√(r²-ab²/4)-√(r²-cd²/4)
