A sector of a circle is some part of a circle that is the enclosed area between two radii and the corresponding circumference between the radii. An angle of 360∘ at the center traces out the circumference of a full circle, so if the cen...
or origin, of the circle to its circumference and encompasses the area of any given angle that also originates from the center of the circle. A sector is best thought of as a piece of pie, and the bigger the angle of the sector, the bigger slice of pie. Each side of the segment...

To solve the problem of finding the area of a sector of a circle with a radius of 4 cm and an angle of 30 degrees, as well as the area of the corresponding major sector, we can follow these steps: Step 1: Identify the formula for the area of a sectorThe area A of a sector of...
We know the area of a circle with a given radius. The sector is a part of the circle and its area depends on the radius of the sector and the angle of the sector. We have the radius and the angle of the sector so we can easily find the area...
Percentages are a function of mathematics that enables you to compare two or more unequal things by expressing both as portions of 100. You can also express the number as a fraction or a decimal. For example, 10 percent is 10 out of 100, or 1/10 or .10. Calculate percentages by dividi...
Sector Perimeter Formula P = 2r + ((2θπr) ÷ 360) r = radius θ = angle in degrees Segment Perimeter Formula P =πrθ/180+ 2r × sin(θ/2) r = radius θ = angle in degrees Pentagon Perimeter Formula P = 5a a = edge length ...
