   Another formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different formulas for finding the circumference: C = πd C = 2πr

   The formula to find the area of a circle is: Area = pi times the radius squared. The radius is a line that starts at the center of the circle and goes to the edge. If you cut the circle in half, the radius would be the distance from the center to the edge. To find the area, we need to know the radius.
