One link in a chain was made from a cylinder that has a radius of 2 cm and a height of 20 cm. How much plastic coating would be needed to coat the surface of the chain link? Use 3.14 for π. a chain link made from a cylinder that has been bent so that its ends are connected, creating a continuous loop A. 251.2cm2 B. 314 cm2 C. 345.4 cm2 D. 471 cm2

A. 251.2cm2

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

the answer is 14ft
