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.
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
