A circle has a radius of four arc in the circle has a central angle of 280° what is the length of the arc

Answer:
20.096 units
Step-by-step explanation:
Given that,
The radius of circle, r = 4
The measure of central angle = 288°
We need to find the arc length. The formula to find the arc length is given by :
[tex]l=\dfrac{\theta}{360}\times 2\pi r\\\\l=\dfrac{288}{360}\times 2\times 3.14\times 4\\\\l=20.096\ m[/tex]
So, the arc length is equal to 20.096 units.
