Perimeter vs Circumference — Comparison Table
| Basis | Perimeter | Circumference |
|---|---|---|
| Definition | Distance around any closed polygon | Distance around a circle |
| Shapes | Squares, rectangles, triangles, polygons | Only circles |
| Calculation | Add all side lengths | 2πr or πd |
| Symbol | P | C |
| Example | Perimeter of square with side 5 = 20 | Circumference of circle with radius 5 = 10π |
Key Points
- Perimeter is the total length of the boundary of any polygon
- Circumference is the special term used for the perimeter of a circle
- Perimeter requires adding individual side lengths
- Circumference uses the radius or diameter and pi for calculation
