I'm pretty sure you are asking for the value of b. Let's actually write it and then solve it:

Solving for b yields:

So,
b = 19.59. If you want the answer in simplified radical form, we can also do that:

So,
b = 8√6 = 19.59

C is the central angle of the arc
R is the radius of the arc
arc length = 2 π R (137/360) = 2.39R
