A circle is a 2 dimensional plane shape that has no sides and no angles. Remember that a circle is not a polygon. To find the area of a circle you need to multiply pi times the radius squared. If you know only the diameter then the formula is pi divided by 4 times the diameter squared. Or when you know only the circumference the formula is circumference squared divided by 4 times diameter.
