Answer: 251.2cm^2
Step-by-step explanation:
Given radius of the cylinder 'r' = 2 cm
Given Height of the cylinder 'h' = 20 cm
Area of the curved surface = 2 π r h
The plastic coating would be needed to coat the surface of the chain link
A = 2 π r h
A = 2 × 3.14 ×2×20
A = 251.2 cm²
Conclusion:-
The plastic coating would be needed to coat the surface of the chain link = 251.2 cm²
