One of the common ways to calculate the value of Pi is by using a circle.
1. The first thing to do is to draw a perfect circle. Make sure you use the right device when drawing your circle so it will be perfect for this method. If you don't know how to draw a perfect circle, I will advise that you start with this.
2. After drawing a circle of any size, the next thing to do is measure the circumference of the circle. If you are wondering what circumference actually means, it is the line that bounds a circle. So, measure the length of that line to get the circumference of the circle.
3. You also need to find the diameter of the circle. The diameter of a circle is any straight line that runs from one point of the circumference to the other point of the circumference of a circle through the center of the circle.
4. Use the formula: π= C/d to calculate the Pi, where C is the circumference, and d is the diameter.
