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
OMB Circular A-130 of information in the operation of Federal programs. The initial release of the Circular provided a policy framework for information resources management (IRM) across the Federal government. Since the time of the Circular's first release in 1985, Congress has enacted several additional laws and OMB issued several guidance documents that related to information technology management in federal agencies. To account for these new laws and guidance, OMB has revised the Circular three times, in 1994, 1996, and 2000. A complete rewrite of the Circular to both update and to correct for known deficiencies has been considered since at least 2005,
