The ratio A/r² would represent

which is the circumference of a circle divided by its diameter.
You can see this because the area of a circle is

r² and if you divided that by the radius squared, you are given pi which is the circumference of a circle divided by its diameter.
38.4 is the area. it’s 8.5 ft long so you do 8.5x2 and you get 17, and then for 10.7 you do 10.7x2 and get 21.4, then you add 21.4 and 17 together.

Answer:
D. $3.
Step-by-step explanation:
We have been given that a box of 7 items costs $20.79. We are asked to find the cost of each item.
To find the cost of each item, we will divide total cost by total number of items.


Upon rounding our answer to nearest dollar, we will get:

Therefore, the cost of each item will be approximately $3 and option D is the correct choice.
