Shift Click the Green Flag and then Press the Green Flag and it will tell you the Pi Estimation. This project places points randomly across a board, and tells you the times it has hit the square, and the times it has hit the circle, then divides the times hit circle by times hit square and finally multiplies by four. This is a great way to estimate Pi.
This was for my math class, just to show and have fun with. Based on a project I saw. https://scratch.mit.edu/projects/211116983/
