Question

A chord is making an angle of 120° at the
centre of the circle. If radius of the circle
is 20 cm, what is the length of the chord?​

Answer 1

Answer:

We know that,

s = rθ

r = 20 cm

θ = 120°

$= 120 \times \frac{\pi}{180}$

s=?

So, s =

$20 \times 120 \times \frac{\pi}{180}$

41.89 cm
