Answer: 9.42 cm.
Step-by-step explanation:
Length of arc is given by :-
, where r= radius and x= central angle subtended by arc.
As per given , we have
![x=30^{\circ}\\\\ r=18\ cm](https://tex.z-dn.net/?f=x%3D30%5E%7B%5Ccirc%7D%5C%5C%5C%5C%20r%3D18%5C%20cm)
Then, the length of arc will be :
![l=\dfrac{30}{360}\times2(3.14)(18)\\\\=\dfrac{1}{12}\times113.04\\\\=9.42\ cm](https://tex.z-dn.net/?f=l%3D%5Cdfrac%7B30%7D%7B360%7D%5Ctimes2%283.14%29%2818%29%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B12%7D%5Ctimes113.04%5C%5C%5C%5C%3D9.42%5C%20cm)
Hence, the length of arc is 9.42 cm.
