How can kids remember the formula for circle area and the formula for circle circumference?
Any formula involving a circle will have "pi" in it. Area = pi* radius * radius Circumference = pi * diameter = pi * radius * 2 ( the diameter is just 2 times the radius) Quick way: A = pi r squared C = pi D
Why is pi used in every circle formula?
By definition Pi is the relation between the radius and circumference of a circle.
What is formula to figure the circumference of a circle?
Circumference = 2 x {pi} x radius = {pi} x diameter
