+354 Pi is an irrational number which is roughly 22/7.
It is used in numerous mathematical equations about circles, $${\mathtt{\pi}}$$d is used to find the circumference of a circle, pi multiplied by the diameter. To find the area of a circle, used $${\mathtt{\pi}}$$r^2. Pi times the radius squared.
The circumference equation can be rearranged to find pi. $${\mathtt{\pi}} = {\frac{{\mathtt{C}}}{{\mathtt{d}}}}$$ where C is the circumference and d is the diameter.
no its about 3.4
