When the central angle is expressed in radians:

 

S = r * theta

Where S is the arc length, r is the radius of the circle, and theta is the central angle in radians.

 

Therefore the arc length in this case is:

\(\dfrac{37\pi}{11}\)

Directly multiply.

 

First edit:

Whoops I did not see that take pi = 3.1416.

Therefore the answer should be \(37/11 \times 3.1416\approx 10.57\)
