Circle Sector and Segment - Math is Fun
WEBThere are two main "slices" of a circle: The "pizza" slice is called a Sector. And the Segment, which is cut from the circle by a "chord" (a line between two points on the circle). Try Them! Area of a Sector. You can work out the Area of a Sector by comparing its angle to the angle of a full circle. Note: we are using radians for the angles.
