Heron's Formula Hero of Alexandra was a great mathematician who derived the formula for the calculation of the area of a triangle using the length of all three sides. This derived formula is called as Heron’s formula . He also extended this idea to find the area of quadrilaterals and also higher order polygons. Derivation of Heron’s formula:
This article is about the shape and mathematical concept. For other uses, see Circle (disambiguation) . "360 degrees" and "360°" redirect here. For other uses, see 360 degrees (disambiguation) . Circle A circle (black), which is measured by its circumference ( C ), diameter ( D ) in cyan, and radius ( R ) in red; its centre ( O ) is in magenta. A circle is a simple closed shape . It is the set of all points in a plane that are at a given distance from a given point, the centre ; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant . The distance between any of the points and the centre is called the radius . This article is about circles in Euclidean geometry , and, in particular, the Euclidean plane, except where otherwise noted.
