WebMar 24, 2024 · Sector of a circle: A Sector is formed by joining the endpoints of an arc with the center. On joining the endpoints with the center, two sectors will be obtained: Minor and Major. By default, we only consider the Minor sector unless it is mentioned otherwise. Semi-circle. A semi-circle is half part of the circle or, WebSection Objective: Find areas of sectors of circles A sector of a circle is a region that is formed by two radii of the circle and their intercepted arc. An easy way to remember the shape of a sector is to think of a slice of pizza. Since a sector is simply a part of a circle, its area can be found by finding the area of the entire circle, and then finding the amount of …
