Answer:
9.9 cm
Step-by-step 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
[tex]= 20\pi \times \frac{57}{360}[/tex]
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
