If a line segment, for example, has endpoints P and Q, it can be represented as PQ― The Formula for Line Segments A line segment, as we are aware, has two endpoints. Now that we have the starting and ending points, we can use the distance calculation to get the exact length of a...

Area of a SectorYou 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.This is the reasoning:A circle has an angle of 2π and an Area of:πr2 A Sector has an angle of θ instead of 2π so its...
It explains how to find the area of a sector of a circle. The formula for the area of a circle is given and the formula for the area of a sector of a circle is derived. Example: Janice needs to find the area of the red section of the circular table top in order to buy the rig...

The area of a sector of a circle is given by the formula:Area of Sector=θ360∘×πr2where θ is the angle in degrees and r is the radius of the circle. In this case, if the angle AOB is given as 60∘, then:Area of Sector=60360×πr2=16πr2 Step 3: Calculate the Area...

• All formula is included. Circular segment - is an area of a circle which is "cut off" from the rest of the circle by a secant (chord). A circular sector or circle sector, is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the min...
