people use pi to find the circumference of a circle.

Pi is an irrational number, so when we're solving with pi, we usually round it to something like 3.14. If we use 3.14 as pi in this problem, we get 84.78.

If pi=3.14, then the circumference is ( 3.14 times the diameter).

radius = diameter/2 circumference = 2*pi*radius or pi*diameter area = pi*radius2
