Of course youknow whata circle looks like, but do you know how it is
defined? A circleis a collection of points that are an equal distance from
one center point. Since circles do not have any corners or vertex points that
define their dimensions, there are special formulas, and a special ratio called
pi(π), that are used when calculating perimeter, area, and volume in circles
and spheres.
