Given the circle with a center O

We will find the arc length of AB

As shown the radius of the circle = r = 9 m

And the measure of the arc = 124°

The arc length will be as follows:

[tex]Arc\text{ }length=(\theta\degree *\frac{\pi}{180})*r=124*\frac{\pi}{180}*9=19.47787[/tex]

Rounding to two decimal places.

So, the answer will be:

Arc length = 19.48 m
