Pi can be calculated using a random sample of darts thrown at a square and circle target.

Calculating pi by yourself There are also fun and simple methods for estimating the value of pi. One of the best-known is a method called “Monte Carlo.” A square with inscribed circle.

Happy Pi Day! Here's how you can empirically determine the value of this well-known mathematical constant.

Pi helps you calculate the area of the circle. To determine the volume (V) of the cylinder - use pi, half the diameter of one circle (r, or radius) two times (two circles) and the height (h).

Using that short version of pi is easy and works fine for simple problems. If you’ve ever used the pi button on a calculator, that probably uses pi rounded to ten decimal places.

Happy Pi Day, the annual celebration of this incredible, mysterious, and irrational mathematical constant.

Swiss researchers said on Monday they had calculated the mathematical constant pi to a new world-record level of exactitude.

Happy Pi Day to you and everyone around you! I always like to find something cool to do with pi on Pi Day. What if I just try to determine the value of pi without using pi (which seems obvious). How ...

The first example of a computer being to calculate Pi was in 1949, when John von Neumann and chums used ENIAC (Electronic Numerical Integrator And Computer) to compute 2,037 digits of Pi.

Talk about perfect timing — a Google engineer revealed she broke the world record for calculating pi on National Pi Day.
