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

C: 345.4 cm²

Step-by-step explanation:

answer: the common difference is -0.10

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
