a circle
wow, that seems easy, like a orange
IT IS NOT!
there r all sorts of formulas (harder than area)
but, if u really want 2 know,
area- pi r square
circum- pi d
formula of circle = (x-x0)square + (y-y0) square= radiius square
(x0,y0) is the center of circle
i think u should just go 2 like google or something and go 2 a website
i love u guys!

If you draw the diameter and any point on the circle, the endpoints of the diameter and the 3rd point will form a right triangle(with the diameter being the hypotenuese)
If you draw two intersecting chords(breaking each chord into two parts) the product of the lengths of the first chord will be equal to the product of the 2nd chord.

Hi. The circumference is ALWAYS equal to EXACTLY the diameter times pi. And they always contain EXACTLY 360 degrees.

They pack the most area into the least perimeter of any plane shape.
