Answer:

The length of the chord is  \frac{88}{7}

Step-by-step explanation:

This question will done by the formula length of a

chord=angle subtended/360*2πr

Now here are given the angle subtended as 120

radius (r) is given as 6 cm

let the length of the chord be l

Now

l=\frac{120}{360} . 2\pi .6\\l=\frac{1}{3} . 12.\pi \\l=4\pi \\

Now we can take the value of \pi =\frac{22}{7}

and we can get the value of l as \frac{88}{7}
