Circumference of a circle 2 pi r
WebArea 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). WebFeb 22, 2024 · The circumference is analogous to a polygon’s perimeter as the principle of measuring both remains the same. The formula is given as: Circumference of a circle = …
