In the definition of pi one needs a perfect circle and measuring devices. These are idealizations to which the real is but a mere shadow. Infinite series that determine pi are also idealizations since we cannot do but finite sums.

In what sense is the number pi a purely human conception? Pi is the ratio
of the circumference of a circle to its diameter. It's been proved
deductively to be transcendental. It's been shown to be the limit of a
particular infinite series. Do you mean it's an artifact of Euclidean
geometry, which is only an idealized approximation of certain aspects of
reality? I'm confused...
