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

251.2cm2
314 cm2
345.4 cm2
471 cm2

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

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
