The needle is  the radius of a circle.
The distance it rotates is a portion of the circumference.
Since there are 360° in a circle, multiply this by 68/360.

The answer is then found as 16*2π*(68/360).
That comes out somewhere below 20cm.
Do it yourself in Excel to get the real answer.

Doesn't that give you 18.98918226 (which is really 19cm)?
