Answer:

x=6

Can someone help me <br> 14. Determine the arc length. Give your answer to two decimal places.

Paul [167]

Answer:

19.48 m

Step-by-step explanation:

The formula that is used to find arc length is:

arc length = 2πr $(\frac{angle}{360})$

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

arc length = 2 × π × 9 × $(\frac{124}{360})$

= 2 × π × 9 × 0.3444

= 19.48 m
