See question number 41 in maths (Paper 1)

The answer given is A which is 22/7 - (pi)
22/7 - pi is also equal to 0 right? So C should also be there in answers.

Am I wrong anywhere?

errr I did not get you bro.....
Ï€ is not equal to 22/7??? Can you please elaborate? I have always used Ï€ = 22/7 in my calculations (as my teachers said). I am very curious about it now.

never mind....I googled it and found out.
(pi) is less than 22/7 ...never knew it.
Btw for your info 355/113 is a more accurate representation of (pi)
