Hi,
By definition, the area of a circle is found through the formula: Area = Pi x r ^ 2 or read a: Pi times r squared.
I hope that helps you out! Please let me know if you have any other questions!
Sincerely,
Andrew

The formula of area of a circle is Ï*r^2,
where Ï=perimeter of a circle/diameter of that,
r=radius=diameter/2

Math lovers-- that's cute :) it's simply pi*radius^2 or 3.14xradiusxradius

pi*r^2
pi ~ 3.14159
r = radius of circle (1/2 diameter)

A = pi*r^2 or pi*d^2/4, where r is radius, d is diameter and pi = 3.1416
