3 days ago · Sector Area = r² × α / 2. But where does it come from? You can find it by using proportions. All you need to remember is the circle area formula (and we bet you do!): The area of a circle is calculated as A = πr². This is a great starting point. The full angle is 2π in radians, or 360° in degrees, the latter of which is the more common angle unit.

The sector is basically a portion of a circle which could be defined based on these three points mentioned below: 1. A circular sector is the portion of a disk enclosed by two radii and an arc. 2. A sector divides the circle into two regions, namely Major and Minor Sector. 3. The smaller area is known as the Minor Sector, whereas the region having ...
In a circle with radius r and centre at O, let ∠POQ = θ(in degrees) be the angle of the sector. Then, the area of a sector of circle formula is calculated using the unitary method. For the given angle the area of a sector is represented by: The angle of the sector is 360°, area of the sector, i.e. the Whole circle = πr2 When the Angle is 1°, area o...
The perimeter of the sector of a circle is the length of two radii along with the arc that makes the sector. In the following diagram, a sector is shown in yellow colour. The perimeter should be calculated by doubling the radius and then adding it to the length of the arc.
