The area of a circle is pi * radius squared. the diameter of a circle is two times the radius, so the radius of this circle is 40. so the area of this circle is 40^2 times pi, which is about 5026.55.

Ashley should get her seeds at garden place as she gets the exact amount of seeds and spends the least amount of money.
first of all I divided 75 by the amount of seeds you get it a packet. then if that was a decimal I rounded it to the larger number (eg. 7.15 rounded to 8)
then I multiplied the cost by that number to get the amount of money itd cost.
so I got in order of the boxes(s=seeds)
75s=$18
80s=$18.4
84s=$21.84
80s=$20
so the best deal is Garden place
