Question

You want to plant vegetables in a circular field where the radius is 58 feet. Each bag covers 355 square feet of land. How many bags will you need at least?A: 30 bagsB: 537 bagsC: 19 bags

Answer 1

To find how many bags you need you need to find the are of the circular field.

The area of a circle is:

`A=\pi\cdot r^2`

The area of the circular field is:

`A=\pi\cdot(58ft)^2=10568.3ft^2`

As 1 bag cover 355 square feet, you divide the area of the field into 355 to find how many bags you need:

`(10568.3ft^2)/(355ft^2)=29.76`Then, you need at least 29.76 or approximately 30 bags
