**The area of a circle is a bit different than that of polygons
in the fact that it is round. However, the area is still measured
in square units.**

**To find the area of a circle, the Greek symbol II ( pi )
is used in the formula Area = pi x radius^2. Pi is approximately
3.14. The radius of a circle is the distance from the center of
the circle to the edge, as shown below in circle A.**
