Could anyone give me a complete and rigorous proof of the formulae for the circumference(2pi*r) and area(pi*r^2) of a cirle of radius r respectively ,or recommend any books on this? I am looking for the kind of proof that any implicit use of the intended formulae are forbidden. Please email me any of your ideas to rwkmung@hk.super.net Thank you.
