The circumference of a circle is 15 ft. find its area writing 3.14 for pi

17.9

Step-by-step explanation:

Area of a circle= C^2/4pi

15^2= 225

4(3.14)=12.56

225/12.56= 17.9

you're missing vital information, add to it so we can solve this problem for you.

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
