If the circumference of the circle below is 72 what is the length of AB (the minor arc)

2πr=72

=2*22/7*r=72

=r=72*7/44=504/44=252/22=126/11=11.45

=πr theta /180=22/7*11.45*60/180

=11.99=12(approx)

answer is (a) 12

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

i just took the test, the correct answer is .. 31.5 in.
