Simplest way to calculate Pi with App Inventor

[Scott Ferguson]

After looking over several formulas to generate Pi that use arc-tangents (http://mathworld.wolfram.com/PiFormulas.html)

and arc-cotangents (http://mathworld.wolfram.com/MachinsFormula.html), I wrote the first formula using App Inventor's atan Math block.

When I solved for Pi, the answer was 180 degrees.

But 180 degrees is Pi radians.

So by using the convert block, 180 degrees can be converted to Pi:
