Step-by-step explanation:
From the question we are told that
The angle of the quadrant is 
The radius of the circle is r =4 m
The angle of the arc is mathematically represented as

The length of the arc is mathematically represented as
![S = 2 \pi r [\frac{z}{360} ]](https://tex.z-dn.net/?f=S%20%3D%202%20%5Cpi%20r%20%5B%5Cfrac%7Bz%7D%7B360%7D%20%5D)
substituting values
' ![S = 2*(3.142) * 4 [\frac{270}{360} ]](https://tex.z-dn.net/?f=S%20%3D%202%2A%283.142%29%20%2A%204%20%5B%5Cfrac%7B270%7D%7B360%7D%20%5D)
