Answer:

c) 345.4 cm²

The plastic coating would be needed to coat the surface of the chain link

= 345.4 cm²

Step-by-step explanation:

Given radius of the cylinder 'r' = 2.5 cm

Given Height of the cylinder 'h' = 22 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 ×2.5×22

A = 345.4 cm²

Conclusion:-

The plastic coating would be needed to coat the surface of the chain link

= 345.4 cm²
