The pi is a ratio and is obtained from a circle. 2 Similarly for a sphere of radius r the surface area and volume enclosed are S 4pir2 3 V 43pir3. The symbol p was devised by British mathematician William Jones in 1706 to represent the ratio and was later popularized by Swiss mathematician Leonhard Euler. If the diameter and the circumference of a circle are known the value of pi will be as p Circumference Diameter.
