A circular sector or circle sector (symbol: ⌔), is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector. Values taken from Ref. BuildSG is a national movement that encapsulates the spirit of collaboration in the transformation of the built environment sector. Such leave The triangle AOX is therefore isosceles and so ∠OXA = a This Circular revokes a number of Circulars, and relevant letters to Personnel Officers, dealing with sick leave and related matters. 4. Area of sector = πr2 × A/360 Radians is a unit less value of an angle. We know that each of the lines which is a radius of the circle (the green lines) are the same length. Therefore 90 + ∠OAC + y = 180 and so ∠OAC + y = 90 In the diagram, θ is the central angle, $${\displaystyle r}$$ the radius of the circle, and $${\displaystyle L}$$ is the arc length of the minor sector. The total area of a circle is . These chains — from raw material extraction to production, transport, consumption and waste — include little or no reuse or recycling. The opposite angles of such a quadrilateral add up to 180 degrees. 1. The name sector is derived from the tenth definition of the third Book of Euclid, in which this name is given to the figure contained by two radii of a circle, and the circumference between them.
