What Is the Area of a Sector?

The area sector is referred as the region of a circle bounded by two radii and the arc between them. When you cut a pizza into pieces, each piece is a sector of a circle. The size of the sector is determined by two factors: the angle formed at the center of the circle, which can be expressed either in degrees or radians, and the radius of the circle.

This basic concept is universally found in almost every branch as geometry, trigonometry and even in some practicals like engineering, architecture or even aerospace.

What is the Procedure for Computing the Area of a Sector?

To calculate the area of a sector manually, the following formula would be required:

Formula:

Area = (1/2) * r² * θ and Area = (θ/360) * π * r²

For degrees:

For radians:

Where:

• r corresponds to the length of the radius of the circle, and
• θ corresponds to the central angle of the sector in degrees or radians.

While the formula itself seems straightforward, hand calculation in the case of sophisticated angles paired with large radii can prove to be tasking. This is why we have the area of sector calculator for this problem.
