Web24 Mar 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, WebA sector of a circle is a portion or part of a circle that is composed of an arc and its two radii. You can compare the sector of a circle to the shape of a pizza slice. A sector is formed when two radii of the circle meet at both ends of the arc. An arc is simply a portion of the …
WebSo the area of the sector over the total area is equal to the degrees in the central angle over the total degrees in a circle. And then we just can solve for area of a sector by multiplying both sides by 81 pi. 81 pi, 81 pi-- so these cancel out. 350 divided by 360 is 35/36. And so …
WebA sector (of a circle) is made by drawing two lines from the centre of the circle to the circumference, and it looks like the usual 'wedge' cut from a cake. There are two special cases. If the angle is 180 degrees then the sector is a semi-circle. If the angle is 360 degrees then the sector is a full circle.
