Which is greater: pi or 22/7?

Hello all
We know that the approximate value of pi is 22/7. Have you ever thought that which is actually greater, pi or 22/7?
Here is a result from calculus (don't worry, if you have not studied that... just enjoy it!)

Here, the given function is positive and since it is integrated in positive limits, so its value is positive.

\frac{22}{7}-\pi> 0

i.e

\frac{22}{7} > \pi
