#### Explanation:

#### Answer:

#### Explanation:

It is an irrational number, a little over

In fact,

We can find some infinite series that we could use to find approximations to

#tan^(-1) x = x - x^3/3 + x^5/5 - x^7/7 +...#

and

#tan (pi/4) = 1#

So:

#pi = 4(1-1/3+1/5-1/7+1/9-1/11+...)#

There are much more effective methods.
