Answer:
Third option.
Step-by-step explanation:
You need to remember that the formula used to calculate the arc lenght is:
[tex]arc\ length=r C[/tex]
Where "r" is the radius and "C" is the central angle in radians.
You need to solve for "C":
[tex]C=\frac{arc\ length}{r}[/tex]
You know the radius and the arc lenght, therefore, you can substitute values to calculate the central angle in radians. Therefore, this is:
[tex]C=\frac{8.0cm}{6.0cm}[/tex]
[tex]C=\frac{4}{3}radians[/tex]
