Understanding Circle Sector Area

A circle sector is a portion of a circle enclosed by two radii and an arc. It's like a slice of pie! To calculate the area of a circle sector, we use the formula:

Area = (θ/360) × πr² (if angle θ is in degrees)
Area = (θ/2π) × πr² = (1/2) × r²θ (if angle θ is in radians)

This calculator simplifies this process, allowing you to quickly find the sector area by inputting the radius and central angle. Whether you're working on geometry problems or practical applications, this tool is here to help!
