A neat challenge, thank you, Ashley @aatalai

It was quite interesting to estimate the points of the square that are inside the circle and calculate respective Pi variance from actual Pi.

I also tried the same estimation with 10^8 rows of random X and Y .

Result

Inside	total simulations	estimation of pi	%variance from actual pi
78542833	100000000	3.14171332	3.8409311299E-03

It seems the approximation method is not very fast...

I tried three different patterns.

Spoiler

1）100 cases as per the given problem.
2)  Created 10,000 cases (100×100) using Append.
   Due to the bias in the original X and Y coordinates, the results were not better than in (1).
3) Generated 10,000 points using a Random function for X and Y coordinates.
  The results were better than in (2), but they varied each time the execution was run.
