Question

Determine the arc length of . Give your answer to two decimal places. You may use theDesmos scientific calculator:

Answer 1

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:

`Arc\text{ }length=(\theta\degree *(\pi)/(180))*r=124*(\pi)/(180)*9=19.47787`

Rounding to two decimal places.

So, the answer will be:

Arc length = 19.48 m
