What is a Sector?
A sector is a portion of a circle enclosed by two radii and an arc. It resembles a pizza slice or a piece of a pie. Sectors are commonly found in real-world applications such as engineering, construction, and even pie charts used in data visualization. Calculating the area of a sector is essential when dealing with circular sections in numerous fields.
Formula for Sector Area Calculation
The area of a sector can be determined using the formula:
Where:
- A = Area of the sector
- θ = Central angle in degrees
- r = Radius of the circle
- π (pi) ≈ 3.1416
Alternatively, if the angle is given in radians, the formula is:
