WebThe area of a regular polygon is half its perimeter multiplied by the distance from its center to its sides, and because the sequence tends to a circle, the corresponding formula–that the area is half the circumference times the radius–namely, A = 1 2 × 2πr × r, holds for a circle. Terminology [ edit] WebJan 10, 2024 · The area of a circle is defined as space or the region it occupies in a two-dimensional plane. It is denoted by A and measured in the square unit, such as m 2, cm 2, etc. Formula: The area of the circle can be determined by the given formula. A = πr2 π r 2. where r = radius of a circle. d = diameter of a circle.
