Answer:
Step-by-step explanation:
The length of an arc can be obtained using the formula: [tex]2\pi r(\frac{\theta}{360})[/tex]
Using this formula we can substitute in the variables as needed.
We know that:
[tex]\pi = 3.14r = 4\theta = 115[/tex]°
So plugging them in we get the following:
[tex]2\pi r(\frac{\theta}{360})[/tex] = [tex]2*3.14 *4(\frac{115}{360})=8.02[/tex]
So the length of the arc [tex]DC[/tex] [tex]= 8.02[/tex]
