Pi is represented using the Greek symbol π


 * Pi first came from:**
 * Greece
 * Eygpt
 * Babolyions
 * Zu Changzhi


 * Formulas that use π :**
 * C= π D (Circumference of a circle)
 * C=2 π R (Circumference of a circle)
 * A= π R² (Area of a circle)
 * S=2 * π rh+ 2 π r² (Surface area of a cylinder)
 * V= π r²h (Volume of a cylinder)
 * V=1/3 π r²h (Volume of a cone)
 * V= 4/3 π r³ (Volume of a sphere)
 * A=4 π r² (Surface area of a sphere)

Pi is the ratio of the circumference of a circle to its diameter. Pi is a non-repeating non-terminating decimal! It is also an indefinite number.Which means that it never repeates and it never ends!
 * To calculate Pi:**
