If you're in a sticky situation and need a good approximation for pi then I recommend:
1/10((987)^1/2)
You're welcome

Thanks! My calculator doesn't have a button for pi so I'll be sure to use this in sticky situations!

wouldn't it be easier to use 3.14159?

3.14159265 is more accurate than a hydrogen atoms width when calculating the radius of the universe (assuming spherical). So just remember that.

3.1416 is the shortest number in decimal of approximating pi that is better than this, finding the square root of 987 is a colossal task compared to the simple mental arithmetic required to use 3.1416
