Question

The angle substended at the center of the chord of a circle of radius 6cm is120° .find the length of the chord

Answer 1

Answer:

6√3 m

Step-by-step explanation:

length of chord

L= 2r sin (A/2)

where r= radius, A = angle subtended at the centre by chord

given , r= 6cm ,A= 120°

=> L = 2× 6× √3/2

= 6√3 cm
