In a circle, what does the ratio A/r^2 represent?
Pepsi [2]
The ratio A/r² would represent \pi which is the circumference of a circle divided by its diameter.

You can see this because the area of a circle is \pir² and if you divided that by the radius squared, you are given pi which is the circumference of a circle divided by its diameter.
