Hi all
In almost all the formulae related with symmetry, we use pi. For example, in case of circle, we use pi, and in case of sphere we use 4*pi.
e.g. E (electric field)= (q * qo) * 1/(4*pi*eps* r^2)
A (circle)= pi*r^2
A (sphere)=4*pi*r^2
My question is: How does pi signify symmetry? Why is the value of pi what it is, and what does this value (22/7) represent? How was this value originally found?
regards
Mr V
