WebArea of a Sector Formula: If a sector makes an angle θ (measured in radians) at the center, then the area of the sector of a circle = (θ × r 2) ÷ 2. Here, θ is in radians. ... we need to know the value of π and r, where r is the radius of the pool. Given: r = 35 feet, and π = 22/7. Using the formula, Circumference (C) = 2πr ⇒ C = 2 × ... WebA sector is formed between two radii and an arc. To find the perimeter, we need to add these values together. \[\text{Perimeter = Arc length + 2r}\] Here, we are given the arc …

WebFeb 23, 2024 · The formula for the perimeter of a sector is 2r [1 + (θ*π)/180]. The maximum possible value θ can reach is 360 o. But at θ = 360, there will be no sector, it … To calculate the area of a sector of a circle we have to multiply the central angle by the radius squared, and divide it by 2. Area of a sector of a circle = (θ × r 2 )/2 where θ is measured in radians. The formula can also be represented as Sector Area = (θ/360°) × πr 2, where θ is measured in degrees.
