The arc length of s in the figure below is 2.18ft.
In the figure below, what is the arc length of s?
Angle length = theta/360 * 2r
The radius r = 1ft
125 degrees = theta
Replace in the formula
Arc length = 125/360 * 2(3.14)* 1
The arc length is 785/360.
2.18ft is the length of the arc.
As a result, the length of the arc is 2.18ft.
