Area of a Sector of Circle = 1/2 × r2θ, where, θ is the sector angle subtended by the arc at the center, in radians, and 'r' is the radius of the circle. Area of Sector Formula Derivation Let us apply theunitary methodto derive the formula for the area of the sector of a ...
This is the simplest method to find the area of the segment of the circle without the usage of the angle made by the chord and thus the area of sector could be found without the usage of angle made by chord. This is done by relating the area of segment to the area of sector....

That slice is a part of the circular pizza, separated across the center. Therefore, a part of the circle cut through the center, making a specific angle with the center known as a sector. How is the circle area related to these parts of the circle? What is the formula for the area ...
Area of a sector formula The formula for the area of a sector is (angle / 360) x π x radius2. The figure below illustrates the measurement: As you can easily see, it is quite similar to that of a circle, but modified to account for the fact that a sector is just a part of a...
In summary, the formula to find the area of a sector in a circle is A = (πr^2θ)/360, where θ is the central angle in degrees. If θ is in radians, the formula becomes A = (r^2θ)/2. The sector area is simply a fraction of the total area of the circle. ...
