Why don't the formulas on this page involve pi?
the other formulas involve non-circular shapes
Is there any geometrical proof for formulas C2Pir APir2 Ps i am not asking for deriving those formulas i am asking for geometric proofs for results calculated by those formulas.?
If you mean the following:- Circumference of circle: 2*pi*radius Area of circle: pi*radius^2 The above formulas are only approximates because the exact value of pi has never been finally determined because pi is an irrational number.
Why don't the other formulas on this page involve pi?
the other formulas involve non-circular shapes
