a pizza slice is an example of a sector that represents afractionof a pizza. There are two types of sectors: minor and major sectors. A minor sector is a sector that is less than a semi-circle, whereas, a major sector is a sector greater than a semi-circle. ...
Otherwise, one of the circular sectors will have smaller area and, for that reason, is going to be called the minor sector. The other, as expected, is going to be the major sector. The goal of this lesson is to explain how to find the area of a sector of a circle, which show up...
Circles, Sectors, Segments Area Of Circles More Geometry Lessons In these lessons, we will learn the area of a sector in a circle the formula for area of sector (in degrees) the formula for area of sector (in radians) how to calculate the central angle of a sector ...
Sectors can have any central angle of up to 360° The central angle can also be measured in radians - when it is measured in radians, the angle can be any value up to 2π radians. When the central angle is measured in radians, the formula for the area is slightly different. ...
How to Find Area of a Sector A sector is a pie-shaped piece of a circle consisting of an arc connecting a radius on either side. Just like a pie, a circle can be subdivided into various sectors. Thearea of a sectoris equal to the central angle divided by 360, times π times the ...

Here is a way to find the formula for the area of a circle:Cut a circle into equal sectors (12 in this example)Divide just one of the sectors into two equal parts. We now have thirteen sectors – number them 1 to 13:Rearrange the 13 sectors like this:...

Sector of a Circle:The sector of a circle is defined as the area enclosed by two radii and the corresponding arc in a circle. There are two types of sectors, minor sector, and major sector. The Number π We know that the circumference of a circle is in constant ratio to its diameter...
If we continued to break the circle up into thinner and thinner sectors, eventually, the bumps would become so small that we couldn’t see them, and the top and bottom of the shape would appear perfectly straight. 10. Now we can use the area formula for a parallelogram to help us find...
