Answer:
First, you should know that the circumference of a circle is 2πr — which, if you think about it, is the arc length subtended by the entire 360∘ circle (70∘=70∘/360∘=19.4¯% of a circle).
So, in general, the arc length subtended by a central angle θ in a circle of radius r is 2πrθ360∘,
if ∠θ is expressed in degrees. The solution is even simpler if θ is in radians; per the arc length formula,
s=rθ.

224.4cm
Step-by-step explanation:
centre angle must be 360 therefore 60*6
arc 27.4*6 = 224.4
