Question

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 1

20.096 units

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 :

`l=(\theta)/(360)* 2\pi r\\\\l=(288)/(360)* 2* 3.14* 4\\\\l=20.096\ m`

So, the arc length is equal to 20.096 units.
