Super-yummy soup, inc. wants to paint their entire soup can red, including the top and bottom. if the diameter of the lid is 5 cm, and the height of the can is 9 cm, what is the approximate total surface area that will need to be painted?

The total surface area of the soup can would be equivalent to the sum of the surface area of the 2 covers plus the surface area of the side.

Surface area of the 2 covers = 2 π r^2

Surface area of the 2 covers = 2 π (2.5 cm)^2

Surface area of the 2 covers = 39.27 cm^2

Surface area of the side = 2 π r h

Surface area of the side = 2 π (2.5 cm) (9 cm)

Surface area of the side = 141.37 cm^2

Total surface area = 39.27 cm^2 + 141.37 cm^2

Total surface area = 180.64 cm^2

step-by-step explanation:

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
