圆周率，一般以π来表示，是一个在数学及物理学普遍存在的数学常数。它定义为圆形之周长与直径之比。它也等于圆形之面积与半径平方之比。是精确计算圆周长、圆面积、球体积等几何形状的关键。分析学上，π 可定义为是最小的 x > 0 使得 sin(x) = 0。常用的 π 10进位近以值为3.1415926，另外还有由祖冲之给出的疏率：及密率：。精确到小数点后第100位的圆周率值 π = 3. 1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679…… Pi This article is about the number. For the Greek letter
see pi (letter). For other uses
see Pi (disambiguation). When a circle's diameter is 1
its circumference is π.The mathematical constant π is an irrational real number
approximately equal to 3.14159
which is the ratio of a circle's circumference to its diameter in Euclidean geometry
and has many uses in mathematics
physics
and engineering. It is also known as Archimedes' constant (not to be confused with an Archimedes number) and as Ludolph's number.
