Answer:

19.48 m

Step-by-step explanation:

The formula that is used to find arc length is:

arc length = 2πr [tex](\frac{angle}{360})[/tex]

In this question, r = 9m and the angle (θ) = 124°. Substitute the values into the formula.

arc length = 2 × π × 9 ×[tex](\frac{124}{360})[/tex]

= 2 × π × 9 × 0.3444

= 19.48 m
