Find the circumference of the circle. Use your calculators value Pi. Round your answer to the nearest tenth.

The circumference of the circle is 75.37 mi.

Solution:

Area of the circle = 452.4 mi²

The value of π = 3.14

Let us first find the radius of the circle.

Area of the circle formula = sq. units

Divide by 3.14 on both sides of the equation, we get

                                       r² = 144.07

Taking square root on both sides of the equation.

                                      r = 12.003 mi

Circumference of the circle = 2πr

                                              = 2 × 3.14 × 12.003

                                              = 75.37884

                                              = 75.37 mi

Hence the circumference of the circle is 75.37 mi.

i not know

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
