Answer:

Area of the circle = 572.3 square ft.

Step-by-step explanation:

Area of a circle is given by the formula,

Area of a circle = πr²

Here 'r' = Radius of the circle

Diameter of circle given in the picture = 27 ft

Radius of the circle = \frac{27}{2}

                                = 13.5 ft

Area of the circle = π(13.5)²

                             = 3.14(13.5)²

                             = 572.265

                             ≈ 572.3 square ft

pantera1 [17]
Martha's total earnings is the sum of her fixed pay pay day and the extra she gains based on the number of toys she sold. Her total earnings may be expressed as,
 
                                        44 + 2n 

Since she desires to earn $80 or more, the inequality is expressed as
 
                                         44 + 2n ≥ 80

Solving for n from the inequality,
 
                                                    n ≥18

Thus, the answer is the first choice.
