Acircle has a radius of 63 what is the arc length intercepted by a central angle that measures 2pi/9 radians

There are two formulas that you need to know:
1. Circumference (length of the circle): 
2. Length of the arc: ,
where r is the radius and a is the angle.
Basically, you need only second formula there to find the answer. Let's use 63 as r,   as a:

So, the answer will be 44 or 

Ithink the answer would be knew

Yuh yeet honestly idk
