Wrong. For two basic reasons.
1. The earth is not a perfect sphere, so you cannot even theoretically
draw a perfect circle on even it's ideal surface.
2. The earth is a gravitating body, and the space in, around and near
it is not perfectly Euclidean.
Not even perfect measurements to infinitesimal precision will yield
exactly pi. But the mathematical computation of one of the several
infinite series will, carried out to infinity, yield pi.
