The radius of circle a is 3 in the radius of circle b is 4 in greater than circle a circle c is 4 in greater than circle b the radius of circle d is 3 in less than the radius of circle c what is the area of all of the circles how many times greater than the area of circle a is the area of circle d

Step-by-step explanation:

Circle A

The radius of circle A is 3 in

r= 3 Inch

Area of Circle A

Circle B

The radius of circle B is 4 inch greater than circle A.

r= 4+Radius of circle A= 4+3 =7 Inch

Area of Circle B

Circle C

The radius Circle C is 4 in greater than circle b.

r= 4+Radius of circle B= 4+7 =11 Inch

Area of Circle C

Circle D

The radius of circle D is 3 in less than the radius of circle C.

r= Radius of circle C -3 = 11-3 =8 Inch

Area of Circle D

Area of Circle A

Area of Circle D

Number of Times by which Area of Circle D is greater than Area of Circle A

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
