Per NCERT, when we write π ≈ 22/7, what does this notation MEAN exactly?
Aπ is the same value as 22/7 always
Bπ is greater than 22/7
Cπ is APPROXIMATELY equal to 22/7 but NOT exactly — 22/7 is good enough for most practical purposes but not equal to π
Dπ is exactly equal to 22/7
Answer & Solution
Correct answer: C. π is APPROXIMATELY equal to 22/7 but NOT exactly — 22/7 is good enough for most practical purposes but not equal to π
Per NCERT, π ≈ 22/7 means 'close but not equal' — emphasised in the chapter. The other options misstate the relationship.
