Debatable.  You could make a case for π/2 as well, since after all a
circle is completely symmetric and you can start with a right angle
quadrant and replicate it three more times to get one.  But π by
itself is the most directly measurable value, as the ratio of a
circle's circumference to its diameter.  Radii are, in general,
tricker to measure on physical circles due to the necessity of
identifying the precise center; it's easier to measure the diameter -
a chord is the diameter when its length hits a maximum - and then
halve that value to get the radius.
