Answer 1

The correct answer is 1.8 pi

Explanation:

Verified by correct test results.

Answer 2

the answer is

`1.8\pi \: or \: 5.6548667765`

Explanation:

so the equation to find arc length is A=

`\pi \: d (m)/(360)`

1. find the diameter by multiplying the radius by 2 to get 10.8

2. plug in the diameter and m stands for the angle measurement, in your case 60

3. when you solve you should get 1.8 pie or 5.6548667765
