Question

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

Answer 1

19.48 m

Explanation:

The formula that is used to find arc length is:

arc length = 2πr
`((angle)/(360))`

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

arc length = 2 × π × 9 ×
`((124)/(360))`

= 2 × π × 9 × 0.3444

= 19.48 m
