Circular segment Circular segment In geometry, a circular segment (symbol: ⌓) is a region of a circle which is "cut off" from the rest of the circle by a secant or a chord. More formally, a circular segment is a region of two-dimensional space that is bounded by an arc (of less than 180°) of a circle and by the chord connecting the endpoints of the arc. Let "R" be the radius of the circle, "θ" the central angle in radians, α is the central angle in degrees, "c" the chord length, "s" the arc length, "h" the sagitta (height) of the
Circular Quay end of Sydney Cove. Circular Quay increasingly became a tourist destination in its own right. Between 1971 and 1989, Colonial Mutual Life acquired land along Circular Quay for a large scale development. The initial, highly controversial design, was revised after the intervention of Prime Minister Paul Keating. In return for reducing the height of the building and adding a colonnade to facilitate public access, the development was permitted to extend further towards the foreshore, with the design finalised in 1992. In 1984, Lionel Todd (Sydney Opera House Stage 3 Architect), proposed his semi-circular quay concept to enhance views of the
