Sector Calculator - Calculate the Area of a Circular Sector

The Sector Calculator is a specialized tool designed to compute the area of a circular sector—a pie-shaped portion of a circle defined by a central angle and radius. This calculator is particularly useful in geometry, engineering, land measurement, and various real-world applications where circular segments need to be quantified.

Key Features:

✔ Easy Inputs – Enter the radius and angle (in degrees or radians) to compute the sector area.
✔ Multiple Units – Supports different measurement units (meters, feet, kilometers, miles, etc.).
✔ Step-by-Step Calculation – Displays the full mathematical process for better understanding.
✔ Accurate Results – Provides precise area calculations with clear unit representation.

How It Works:

1. Enter the Radius (r) – The distance from the center to the edge of the circle.
2. Select the Radius Unit – Choose from meters, centimeters, kilometers, miles, yards, feet, or inches.
3. Enter the Angle (A) – The central angle that defines the sector.
4. Choose Angle Unit – Degrees (°) or radians.
5. Click "Calculate" – Instantly get the sector area with a detailed breakdown.

Formula Used:

The area of a sector is calculated using:Area=(A2π)×π×r2=A×r22Area=(2πA​)×π×r2=2A×r2​

Where:

• AA = Central angle (in radians)
• rr = Radius of the circle

Practical Applications:

• Land Surveying – Measure plots of land with circular boundaries.
• Engineering & Architecture – Design curved structures, arches, and circular segments.
• Mathematics & Education – Learn and verify geometric principles.
• DIY & Construction – Calculate materials needed for circular designs.

Whether you're a student, engineer, or hobbyist, the Sector Calculator simplifies complex circular area calculations in seconds! 🚀
