Per NCERT, what is the value of the C/D ratio (circumference ÷ diameter) for a circle?
Aπ (pi), an irrational number approximately 3.14159...
BExactly 22/7
CA different value depending on the size of the circle
DExactly 3.14
Answer & Solution
Correct answer: A. π (pi), an irrational number approximately 3.14159...
C/D = π for every circle (constant, irrational). 22/7 and 3.14 are approximations only.
