The area of the polygons compare to π in the way that as
more angles and sides are added to a polygon the polygon becomes closer to a
circle; the perimeter slowly changes to circumference. Π is used to find the
area and circumference of a circle, so as polygons come closer to becoming circles
π becomes more strongly associated to the polygon. You can even use π to find
the approximate area of a circle if you use the same formula (as you would to
find the area of a circle) on a polygon. Another way to go about it is like
this…
You can find the area of a circle if you know the circle’s
circumference by using these steps:
<span>1. Divide the
circumference by π to find the diameter of the circle.</span>
<span>2. Divide the
diameter by 2 to find the radius of the circle.</span>
<span>3. Now that you
have the radius you can use the formula Area= πr2 to find the area of the
circle.</span>
