Here the symbol π (Greek letter pi) denotes the constant ratio of the circumference of a circle to its diameter or of the area of a circle to the square of its radius. Since the area of a regular polygon is half its perimeter times its apothem, and a regular polygon approaches a circle as the number of sides increase, the area of a disk is half its circumference times its radius (i.e. 1⁄2 × 2πr × r)."@en }
