WebThe outer circle would form a line having length 2πr forming the base. The height would be ‘r’ Therefore the area of the right-angled triangle formed would be equal to the area of a circle. Area of a circle = Area of triangle = (1/2) × b × h = (1/2) × 2π r × r. Therefore, Area of a circle = πr 2.
