The diameter of a circle is 14 feet what is the circles area

area of a circle  = 153.958 ft²

Step-by-step explanation:

given that the diameter of a circle = 14ft

area of circle = ?

recall that the fomular for finding the area of a circle is =  πr²

note the radius was not given , and recall that radius = 1/2 × Diameter

radius = 14/2

radius = 7ft

area of a circle  = πr²

area of a circle is = 22/7 × (7)²

area of a circle = 3.142 × 49

area of a circle  = 153.958 ft²

Therefore the area of the circle whose diameter is 14ft is evaluated to be  153.958 ft²

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

true !
