Answer:
20.7694180987 - unrounded
20.77 - rounded
Explanation:
The formula for arc length is: 2 times pi and r time theta over 360. This means that it would be 2(pi)(14) (85/360).
2 times pi times r equals 87.9645943005
multiply your result by (85/360) to get your result
Divide the given angle by 360, then multiply by 2 x radius x PI:
85/360 x (2 x 14 x PI)
85/360 x 87.96459 = 20.769 ( Round answer as needed)
Or if needed in terms of pi : 6.61PI
You did not say how the answer needed to be rounded.
