Per NCERT, what does it mean to say that π is an IRRATIONAL number?
Aπ changes value depending on the circle
Bπ has no decimal expansion at all
Cπ cannot be written as a fraction a/b where a and b are integers (b ≠ 0)
Dπ equals 22/7 exactly
Answer & Solution
Correct answer: C. π cannot be written as a fraction a/b where a and b are integers (b ≠ 0)
Irrational means π ≠ any integer fraction (per NCERT). Its decimal expansion is infinite and non-repeating.
