Interpreting your expression as

when
approaches zero, the numerator approaches 3:

The denominator approaches 0, because 
Moreover, we have

So, the limit does not exist, because left and right limits are different:

Answer:
The arc length of the entire circle would be 2*PI*9
We need to know the arc length of 1/3 of the circle so we calculate
arc length = (2 * PI * 9) / 3
arc length = 2 * PI * 3
arc length = 6 * PI
arc length = 18.8495559215
