Answer:

Explanation:

The length of an arc can be obtained using the formula:
$2\pi r((\theta)/(360))$

Using this formula we can substitute in the variables as needed.

We know that:

$\pi = 3.14r = 4\theta = 115$ °

So plugging them in we get the following:

$2\pi r((\theta)/(360))$ =
2*3.14 *4((115)/(360))=8.02

So the length of the arc

= 8.02
