The following formula calculates the area of a circle:

PI( ) * RADIUS ^ 2

Returns

The value of PI (3.1415926536), the ratio of a circle's circumference to its diameter.

Example

The following examples employ the PI function:

Example 1

PI( ) * 7 = 21.99 (circumference of a circle with a diameter of 7).

Example 2

PI( ) * 36 ^ 2 = 4071.50 (area of a circle with a radius of 36).
