You calculate the area of a circular sector using the formula 

A = \text{π}r^{2} \times \dfrac{\text{α}}{360^\circ}

. You’ll find explanations of the terms and examples in this video.

How Do You Calculate the Area of a Circular Sector?

You calculate the area of a circular sector using the formula A = πr² x α/360 degrees. You’ll find explanations of the terms and examples in this video. 

A set of points that has the same fixed distance from a point, called the center of the circle.

A portion of a disk that is bounded by two radii and a circular arc. Also known as simply sector for short

Any line segment from the center of a circle to its circumference

A measure of the separation between two rays which share a common starting point

The ratio of a circle’s circumference to its diameter. Its value is approximately 3.14, andits symbol is the Greek letter \pi
