How do i get the area of a circle

WebIn a circle with radius r and center at O, let ∠POQ = θ (in degrees) be the angle of the sector. Then, the area of the circle is calculated using the unitary method. When the angle of the sector is 360° (i.e., the whole circle), Then the area of the sector is: A = π r 2. When the angle is 1°, then the area of a sector is: A = π r 2 360 ∘.
