This means Chunks cut off by joining any two points on the circle are segments. Whereas, a cut carried off from between two points on the circle by a "chord" is called a Segment. Therefore, a circle's radius is invariably half the length of its diameter and its diameter is always double the length of its radius.Ī semicircle (half circle) and a Quadrant (Quarter of a circle) are two main types of Sector:īesides, There are primarily two "portions" of a circle: Of which, the "pizza" slice is known as the Sector.
Take Notice of Diameter - it is actually two radii combined. Radius - A line that runs through the midpoint to the exterior of the circleĭiameter - A line extending across the circle and passes through its midpoint. To ace over the calculation of area of sector, understanding the anatomy of the circle is the key.Ī Midpoint - It is the most crucial one as it is the connecting dot positioned right in the circle's centre. Similarly, cut the cake into Slices and you will get the sector of a circle.Ĭrack the Area of a Sector in Simple Few Steps Divide the circle into pieces and you will get a sector. A variety of foods that we eat resembles the sector of a circle, typically because they replicate circles.Ī circle consists of an interior, its area. To better understand what a sector of a circle is, here is a specimen from the real-life examples of food. It typically involves a province (sector) encompassed by 2 Radii and 1 Arc lying between the radii. A sector is much the same as a “pie” or a "pizza slice".
