Circles and area
WebComparing a Circle to a Square. It is interesting to compare the area of a circle to a square: A circle has about 80% of the area of a similar-width square. The actual value is (π /4) = 0.785398... = 78.5398...% Why? … WebArea of sector = θ 360 ∘ × π r 2. If is measured in radians, then “the area of a sector of a circle formula” is given by. Area of sector = 1 2 × θ × r 2. Perimeter of sector = 2 r + θ 360 × 2 π r.

WebSo, the area of one half of the intersection is the area of a circular segment with angle θ = 2 π 3 and radius r, which gives an area of r 2 2 ( θ − sin θ) = r 2 2 ( 2 π 3 − 3 2) and so the area of the entire intersection is twice this. … WebApr 11, 2024 · The sector area formula may be found by taking a proportion of a circle. The area of the sector is proportional to its angle, so knowing the circle area formula, we can write that: α / 360° = Sector Area / Circle Area. Angle conversion tells us that 360° = 2π. α / 2π = Sector Area / πr². so: Sector Area = r² × α / 2
