One link in a chain was made from a cylinder that has a radius of 2.5 cm and a height of 22 cm. How much plastic coating would be needed to coat the surface of the chain link? Use 3.14 for π. 251.2 cm2
314 cm2
345.4 cm2
471 cm2

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
