   What is a sector in a circle?

   • A sector is a part of a circle enclosed by two radii and an arc. In the figure below are three sectors of a circle. We see sectors all around us in our everyday lives. A slice of pizza is a sector; a window pane divides a circular window into sectors.

   How to calculate area of sector of a circle without an angle?

   • l = (θ/360) × 2πr or l = (θπr) /180. Area of a Sector of a Circle Without an Angle Formula When the angle of the sector is not given and the length of the arc of a sector of a circle is given we can calculate the area of the sector of a circle by using length. Assuming the length of an arc, 'l' and radius of a circle is 'r'.

   What is the difference between a minor sector and a major sector?

   • A sector of a circle is called the minor sector if the minor arc of the circle is a part of its boundary. It is the sector with a smaller area. The angle of a minor sector is less than 180 degrees. A sector is called the major sector if the major arc of the circle is a part of its boundary. It is the sector with the greater area.

   How to find the area of a sector?

   • Let’s learn how to find the area of a sector of a circle. The formula for determining the area of a sector is given in two ways, with an angle and without an angle. If the radius of a circle is given as “r” and the angle of the sector is given as . This angle is made by the two radii at the center.

   A 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 circumference of the circle. Sector of a Circle Definition.
