The relation between circumreference and radius of circle

Is of course Pi but Pi is irrational and have a unfinished decimal
expansion. How much work has been done in geometry to find a none
irrational substitute to Pi by replace the radius with some other
property of the circle that do not lead to a irrational expression?

Well my quetsion maybe even not correct stated, but if there was a
relation between some aspect of a polygon and the circumrefrence that
had closed decimal expansion, would that be used instead of the radius
and Pi to calculate the circumreference and area of the circle?

So is it possible that there could be another expression to calculate
circles circumreference and area that is not an approximation, by
using rounded numbers?
