Each bag of soil covers 9.42 square feet.
The radius of the circular garden is equal to the pie times of the square of the radius.
The radius of the circular garden is;
[tex]\rm Area = \pi r^2\\\\Area = 3.14 \times (4)^2\\\\ Area = 3.14\times 16\\\\Area =50.24[/tex]
Therefore,
The number of bags of soil will she need to buy is;
[tex]\rm = \dfrac{Area }{Soil \ covers}\\\\= \dfrac{50.24}{9.42}\\\\= 5.33\\\\= 6 \ bags \ apporx[/tex]
