Area of a circle is equal to : (Pi)(R^2)
It's read as Pie-R-squared
Pi's value is 3.1416
The radius' value is depending on the given problem.

The region inside a circle, a disk, has an area of Ïr2 when the circle has radius r. Here the symbol “Ï” denotes, as usual, the constant pi, defined as the ratio of the circumference of a circle to the diameter.
area = 2 x Ï x R squared
