a circle has a radius of 4m. find the circumference of the circle show your worth and strictly answering used 3.14 for pi​

25.12

Step-by-step explanation:

Circumference (C) = 2πr

Where r = radius

We want to find the circumference of a circle with a radius of 4m ( this means that r = 4 )

To do so we simply plug in the value of r into the circumference formula

Formula: C = 2πr

r = 4 ( note that it says use 3.14 for π )

plug in values

C = 2(3.14)(4)

Simplify

C = 25.12

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

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
