Answer:

9.9 cm

Explanation:

As we can see in the diagram that the total of straight line has 180 degrees

Therefore ∠RPQ is 180 degrees - 123 degrees = 57 degree

And, arc length is equivalent to the circumference of circle i.e


= 20\pi * (57)/(360)

where,

Pie = 22 by 7

Therefore the approximate length of QR is 9.9 cm

We simply applied the above calculation so that we get to know the length and the same is to be considered
