Atriangle is placed in a semicircle with a radius of 7mm , as shown below. find the area of the shaded region. use the value 3.14 for pi , and do not round your answer. be sure to include the correct unit in your answer.

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
