A flower garden is shaped like a circle. Its radius is 20 yd . A ring-shaped path goes around the garden. The width of the path is 5 yd .
The gardener is going to cover the path with sand. If one bag of sand can cover 7 yd^2 , how many bags of sand does the gardener need? Note that sand comes only by the bag, so the number of bags must be a whole number. (Use the value 3.14for .)

Answer:

101 bags

Step-by-step explanation:

Amount of sand=flower garden and path area - flower garden area

radius of the flower garden and path is 25 so the area is 1962.5

radius of the flower garden is 20 so the area is 1256

1962.5-1256 is 706.5

706.5 divided by 7 is 100.928571429 but it needs to be a whole number

101 bags is the answer because 100 bags will not fit the whole thing
