Examples. Definition: The part of a circle enclosed by two radii of a circle and their intercepted arc . A circular sector or circle sector (symbol: ⌔), is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector. The formula for sector area is simple - multiply the central angle by the radius squared, and divide by 2: Sector Area = r² * α / 2; But where does it come from? Calculate the total area of a Spherical sector. Sector area is found A = 1 2 θr2 A = 1 2 θ r 2, where θ θ is in radian. Example. Hope it helps...All the best! Area of major sector = π r 2 - area of minor sector; Angle described by a minute hand in one minute = 6 ∘ ; Angle described by hour hand in one minute = 1 2 ∘ ; The sum of the lengths of arcs of major and minor sectors of a circle is equal to the circumference of the circle. Area of a circular sector. If the central angle is less than 180 degrees or radians, we have a minor sector, whereas if it's greater than 180 degrees, that's greater than radians, we have a major sector. For example, a pizza slice is an example of a sector representing a fraction of the pizza.There are two types of sectors, minor and major sector. Area of minor sector _____. Adding to that, what is area of major sector? A minor sector is less than a semi-circle sector, whereas a major sector is a sector that is greater .

The area of the major segment can be calculated by taking the area of the minor segment from the total area of the circle. Sector of a circle: A Sector is formed by joining the endpoints of an arc with the center. . 2) Sum of the areas of major and minor sectors of a circle is equal to area of the circle. The major sector is the also the region having a greater area. Ans: If the central angle of the minor sector is \(θ\) then, the formula of the minor sector is \(=\frac{\theta}{360^{\circ}} \times \pi r^{2}\) where \(r\) is the radius of the circle. In the diagram, θ is the central angle in radians, the radius of the circle, and. The arc length formula is used to find the length of an arc of a circle; l=rθ l = r θ , where θ is in radians.Sector area is found A=12θr2 A = 1 2 θ r 2 , where θ is in radians. Answer:the anwer is Theta by 360× pi×r^2 =minor sectorArea of circle - area of minor sector = area of major sector. It also separates the area into two segments - the major segment and the minor segment. Area of a circle = πr 2. The area of a sector of a circle is also called a circular sector. L = 300/360 x ( Ԉ R x 2 ) xThis fraction is 300 / 360 L = 0.8333 x ( 3.1416 x 10 x 2 ) The large remaining part of thiscircle is called a "MAJOR Sector". With degrees, a whole circle made an angle of 360°. Sectors, segments, arcs and chords are different parts of a circle. True. If the area of a sector is more in circle then it is known as a major sector. Step 1: Calculate the area of the whole circle. Then area of shaded part = πR 2 - πr 2 = π (R 2 - r 2) = π (R + r) (R - r) Minor arc and Major Arc: An arc length is called a major arc if the arc length enclosed by the two radii is greater than a semi-circle.
