Definition Of Sector. The area between an arc and two radii of a circle is called Sector. More About Sector. Sector can also be referred as Wedge. Asector is the region enclosed by two radii and an arc. The two radii divide the circle into two sectors called a major sector and a minor sector.
Aug 3, 2023 · Sector of a Circle Formula. Let us solve some examples to understand the concept better. The length of an arc is 64 mm. Find the area of the sector formed by the arc if the circle’s radius is 15 mm. Solution: As we know, Area (A) of a sector = r × L/2, here r = 15 mm, L = 64 mm. = (15 × 64/2) mm 2. = 480 mm 2.
Then, the area of a sector of circle formula is calculated using the unitary method. For the given angle the area of a sector is represented by: The angle of the sector is 360°, area of the sector, i.e. the Whole circle = πr 2. When the Angle is 1°, area of sector = πr 2 /360° So, when the angle is θ, area of sector, OPAQ, is defined as;
Learn how to define and measure circles, angles, arcs, sectors, and chords in this unit of Khan Academy's Geometry course. You will also discover how to use radians, inscribed angles, and tangents to solve various problems involving circles.
A circle broken into seven sectors. Six of the sectors have a central angle measure of one radian and an arc length equal to length of the radius of a circle. The seventh sector is a smaller sector. The seven sectors represent the little more than six radians that it takes to make a complete turn around the center of a circle.
