I have seen that:

  1. $\pi = 22/7$

  2. $\pi = 3.14\ldots$

  3. $\pi = 17 - \sqrt{192}$.

  4. $22/7 \gt \pi$

  5. $22/7 \lt\pi$

My brain storming doubt was, is A = B? Is B = C? Is C= A = B? how D and E are correct or myself is totally wrong? Please discuss.

I think, if any one is wrong, then whole mathematics may be wrong, especially things which we dealt with $\pi$. These questions there from long back in my mind. I think, by your help, I can end by your solutions or reasoning.

Thanks in advance.
