Question 759679
Formula = Angle/360 = length of arc/ Pi*Diameter = area of sector/Pi*r^2
Using the first two
Angle/360 = length of arc/ Pi* D 
Pi/4 = 45 degrees
45/360 = length of arc/Pi * 34
45 * Pi * 34/ 360 = length of arc
 4806.648/360 = length of arc
     13.3518 = length of arc
     13.35 units.
Hope this helps.
