It is a line which intersects the circle in two points on the boundary.Ī part of the circumference is referred to as an arc. The space enclosed by the boundary of the circle is termed as the area of the circle. It is point which is exactly in the center of the circle, equidistant from every possible point on the boundary of the circle. It is line which passes through the center of the circle and has its endpoints on the boundary of the circle. It is the distance between the center of the circle and its boundary. It is a line that touches the circle at exactly one point externally and is perpendicular to the radius. It is a line segment whose endpoints lie on the circle itself. When a curved line having its endpoints joint to each other makes a round figure, all of whose points are equidistant from a fixed point or center, a circle is formed. Understanding a circle in geometric terms: Definition of Circle: It has fascinated mathematicians since ages and is a shape that is seen, studied, found and used beyond theory. It also took influence from the Latin word circulus, which again means ring. The term circle finds its roots in the Greek word kirkos, which means hoop or circle. It has undeniably seeped into our day to day lives with its overwhelming versatility. Especially useful for quality checking on machined products.įor calculating the area or centroid of a planar shape that contains circular segments.Be it the wheels of a vehicle, the ripples that get formed when a raindrop hits a pond, cosmic bodies like planets, food items like pizzas and donuts, coins or even bangles, the circle has always existed in our lives since time immemorial.

One can reconstruct the full dimensions of a complete circular object from fragments by measuring the arc length and the chord length of the fragment.

In the design of windows or doors with rounded tops, c and h may be the only known values and can be used to calculate R for the draftsman's compass setting. The area formula can be used in calculating the volume of a partially-filled cylindrical tank laying horizontally. These can't be calculated simply from chord length and height, so two intermediate quantities, the radius and central angle are usually calculated first. Usually, chord length and height are given or measured, and sometimes the arc length as part of the perimeter, and the unknowns are area and sometimes arc length. Let R be the radius of the arc which forms part of the perimeter of the segment, θ the central angle subtending the arc in radians, c the chord length, s the arc length, h the sagitta ( height) of the segment, d the apothem of the segment, and a the area of the segment.

More formally, a circular segment is a region of two-dimensional space that is bounded by a circular arc (of less than π radians by convention) and by the circular chord connecting the endpoints of the arc. In geometry, a circular segment (symbol: ⌓), also known as a disk segment, is a region of a disk which is 'cut off' from the rest of the disk by a secant or a chord.

Slice of a circle cut perpendicular to the radius A circular segment (in green) is enclosed between a secant/chord (the dashed line) and the arc whose endpoints equal the chord's (the arc shown above the green area).
