Respuesta :
Answer: B) 7.99 meters
Step-by-step explanation:
The formula to find the length of arc having center angle 'x' is given by :-
[tex]l=\dfrac{x}{360^{\circ}}\times C[/tex], where C is the circumference of the circle.
Given : Circumference : 23 meters
Central angle subtended by arc AB: [tex]x=125^{\circ}[/tex]
Now, the length of arc AB is given by :-
[tex]l=\dfrac{125}{360}\times 23=7.98611111111\approx7.99\text{ meters}[/tex]
Hence, the length of arc AB = 7.99 meters.
