What is Pi in maths???

If you have a circle the line that goes across it is called the diameter. Take that line and put it on the perimeter. A perimeter is the outside of a circle, also known as the circumference. You will need 3 of the diameters and then a little bit more (0.142) to go around the whole circle. That is why Pi is 3.142 - it is 3.142 diameters to get round the circumference of a circle. ⭕️
