If you notice that there is symmetry in the numbers 0 to 10 this is a good place to start with what I want to talk about. I want to talk about the circle. If we need a technically correct circle one would need to see the symmetry of 0 to 10 and more correctly 0 to 5 and from this point 10 to 5 in a line. If 10 is our circumference of a perfect circle then we need to find our diameter. We know that there are 4 points in a circle so 2.5 is our diameter. C/d equal pi. Which would be 4 in this case. If you can guide me to where im steering wrong that would be appreciated. I think the question of a circle is symmetry and not a unusual number.
