Circumference is normally used for circles and is asking for the outer edge of the circle while area is the inner part of the shape formulas for circumference is 2 x PIE x radius While area is length x breadth for most shapes or PIE x (radius)squared so both have to do with measurements and differ in what the measurements are focusing on
Circumference is the distance around a circle, or the perimeter. Area is the space inside the circle. Area has square units, circumference does not. They both have π in the formula.
