Area of a segment of a Circle formula = Area of Sector - Area of Triangle. If the two lines are formed at a 180 degree angle then the sector is often referred to as a semi-circle. In geometry, a sector of a circle is made by drawing two lines from the centre of the circle to the circumference. Note: A circular sector or circle sector, 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. How to Find the Arc Length. How to Calculate The Area of Sector with This Tool? Circular segment - is an area of a circle which is "cut off" from the rest of the circle by a secant (chord). Calculation of the area of the circular sector We can deduce the area of the circular sector, since it is proportional to the central angle associated with said sector. Customer Voice.
