Find the length of each highlighted arc. leave your answers in terms of pie.

Method 1:

The formula for arc length is:

× 2πr

AB is 45 degrees

r (radius) = 14 cm

^^^Plug this into formula given above

× 2π(14)

× 28π

Method 2:

The formula for arc length is:

s is the arc length

r is the radius

theta will be in radians

In this case:

s = unknown

r = 14 cm

theta = 45 degrees (converted to terms of pi: 45 × --->   )

^^^Plug this into formula given above

Cross multiply

s * 1 = * 14

s =

s =

s =

^^^This is your arc length

Hope this helped!

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
