In a circle of radius 20 cm, the distance between a pair of equal and parallel chords is 24 cm. Findhow long the chords are.

Answer»

Radius=20cmDistance between chords =24cmLet the length of chord is 2xHalf the length of chord is x(base)Distance of each chord from center is 12cm(perpendicular)Radius is 20cm(hypotenuse)From pythagoras,20^2=x^2 + 12^2400=x^2+144400-144=x^2256=x^2x=16So, the length of chord is 2x=32cm

nice yes this answers
