WebbArea of a circle, A = πr 2 square units. Circumference / Perimeter = 2πr units. Area of a circle can be calculated by using the formulas: Area = π × r 2, where 'r' is the radius. Area = (π/4) × d 2, where 'd' is the diameter. Area = C 2 /4π, where 'C' is the circumference (sometimes referred to as perimeter). WebbThe perimeter of a circle, often called the circumference, is proportional to its diameter and its radius. That is to say, there exists a constant number pi, π (the Greek p for perimeter), …
