Pi has a value of 3.1415........ which has a decimal expansion that is both non recurring and non terminating and goes on forever. So, by the definition Pi is an irrational number.

However, to solve practical sums and for our satisfaction we consider the value of pi as 22/7 and 3.14 so that they become rational as they can be shown in the form p/q where both p and q are integers.

HERE IS THE ANSWER;

◆ As you know that π is a irrational number as it's decimal expension is non- terminating & Non- repeating.

◆ But these statements are actually true because we have assumed the APPROPRIATE value of π as 22/7 to make calculation easier.

◆ If you divide 22/7 then it's decimal expension will come 3.14... which as approximately value equal to π.

HOPE IT HELPS

DonDj: yes offcorse but its decimal expension if u say then it will come non term. non repleating

DonDj: Something else ?

DonDj: plz mark it as brainlest if it helped u

MaxTheWizard123: Irrational numbers can't be represented as a fraction with integers as the numerator and denominator. 227 is a fraction with integers as it's numerator and denominator. Therefore, 227 is not irrational.

227 is often used as an approximation for π. However, 227 does not equal π. 227≈3.1428571429, while π≈3.1415926536.
