Explanation:
The Chinese mathematician Zu Chongzhi (AD 420500) calculated approximations to
#3.1415926 < pi < 3.1415927#
He identified two rational approximations to
#22/7 = 3.bar(142857)#
#355/113 ~~ 3.1415929#
Nowadays we tend to use the following approximations:

#3# for a quick rough and ready estimation. 
#3.14# or#22/7# for calculations for simple practical use.
