Answer: B) 7.99 meters
Step-by-step explanation:
The formula to find the length of arc having center angle 'x' is given by :-
, where C is the circumference of the circle.
Given : Circumference : 23 meters
Central angle subtended by arc AB: ![x=125^{\circ}](https://tex.z-dn.net/?f=x%3D125%5E%7B%5Ccirc%7D)
Now, the length of arc AB is given by :-
![l=\dfrac{125}{360}\times 23=7.98611111111\approx7.99\text{ meters}](https://tex.z-dn.net/?f=l%3D%5Cdfrac%7B125%7D%7B360%7D%5Ctimes%2023%3D7.98611111111%5Capprox7.99%5Ctext%7B%20meters%7D)
Hence, the length of arc AB = 7.99 meters.
