Find the perimeter of a sector
WebFeb 16, 2024 · The formula for finding the perimeter of a circle sector is: P = \pi *R* \dfrac {\alpha^o} {180^o} P = π ∗ R ∗ 180oαo. Or. P = 2R + \alpha *R P = 2R + α ∗ R. Where … WebTo calculate the perimeter of an arc (part of a circle) from the angle you can calculate the fraction of the circle. In the example above we can work this out as follows: 60/360 x 2π x 4 = 4/3 π cm = 4.19cm (to 3 s.f.) The …

WebMar 30, 2024 · A sector is a part of the circle. Perimeter of sector will be the distance around it. Thus, Perimeter of sector = 𝜃r + 2r. = r (𝜃 + 2) Where 𝜃 is in radians. If angle is in degrees, 𝜃 = Angle × π/ (180°) Let us take … http://www.cleavebooks.co.uk/scol/calsect.htm
WebA sector (of a circle) is made by drawing two lines from the centre of the circle to the circumference, and it looks like the usual 'wedge' cut from a cake. There are two special cases. If the angle is 180 degrees then the sector is a semi-circle. If the angle is 360 degrees then the sector is a full circle. Clearly the angle cannot be greater ... WebSep 15, 2024 · As with arc length, we have to make sure that the angle is measured in radians or else the answer will be way off. So converting θ = 117 ∘ to radians and using r = 3.5 in Equation 4.3.1 for the area A of the sector, we get. θ = 117 ∘ = π 180 ⋅ 117 = 2.042 rad ⇒ A = 1 2 r2 θ = 1 2 (3.5)2 (2.042) = 12.51 m2 . For a sector whose angle ...
