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. ...

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 of a circle?Area of Circle FormulaThe formula for the area of a circle ...
The first round yellow area is a fan. The area of a sector is equal to (Angle AOB / 360°) • π • r2 Green area (second circle) is a part Each area is equal The area of the sector minus the area of the triangle AOB
Sector of a Circle The area enclosed by an arc and the two radii joining the arc’s endpoints with the centre is called the sector of the circle. When the major arc forms the sector, it is called the Major Sector and when the minor arc forms the sector, it is called a Minor Sector...
We compute explicitly all the contributions to this formula coming from the different parts of the sector. In the process, we obtain an explicit expression for the heat kernel on an infinite area sector using Carslaw-Sommerfeld's heat kernel. We also compute the zeta-regularized determinant of ...
