A) 0.0707 m2
B) 0.0616 m2
C) 0.0524 m2
D) 0.0491 m2
As per IS 1239 (Part 1)-2004 for Pipes, the internal diameter is 300 mm or 0.3 m.
The internal radius r = (Internal diameter/2) = 0.3/2 = 0.15 m
The internal cross-sectional area A = πr2
= π x (0.15)2
= 0.0707 m2
Therefore, option A is the correct answer.
