Question

radius of a circle is 20cm difference between two equal and parallel chords is 24 cm find the length of the chords​

Answer 1

Answer:

Radius=20cm

Distance between chords =24cm

Let the length of chord is 2x

Half 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 + 12^2

400=x^2+144

400-144=x^2

256=x^2

x=16

So, the length of chord is 2x=32cm
