Web9 Feb 2024 · The arc length formula is used to find the length of an arc of a circle; ℓ = θr ℓ = θ r, where θ θ is in radian. The circle’s circumference is C = 2πr C = 2 π r, as the centre angle is 2π 2 π. Correspondingly, when the centre angle is θ θ, the arc, which is a part of the circumference, is calculated as; ℓ = 2π × θ 2πr ... WebArc length is just a fraction of the circumference of the whole circle (\(\pi d\) or \(2 \pi r\)). Sector area is just a fraction of the area of the whole circle (\(\pi r^2\)). Example 1 (calculator) A sector has radius 5 cm. The angle at its centre is 41°. Calculate: (a) the arc length (b) the sector area. Show answer

WebIf the angle is 360 degrees then the sector is a full circle. Clearly the angle cannot be greater than 360 degrees. Where (for brevity) it says 'radius', 'arc' and so on, it should, more correctly, be something like 'length of radius' or 'arc-length' etc, and 'angle' means 'angle at the centre'.
