Free help from wikiHow. Sector is the portion of a disk enclosed by two radii and an arc. This website uses cookies to ensure you get the best experience. The figure below illustrates the measurement: As you can easily see, it is quite similar to that of a circle, but modified to account for the fact that a sector is just a part of a circle. FAQ. Sector of a Circle Area Calculator 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 minor sector and the larger being the major sector. Arc length . Select the input value you want, then enter their values. This is how we can find the area of the shaded region. Area of a Kite Calculator. Angle in degrees. Calculate the area of a sector: ... To calculate arc length without the angle, you need the radius and the sector area: Multiply the area by 2. Area of a hyperbolic arch. In the below area of a sector of a circle calculator, enter the central angle and radius in the respective input boxes and click calculate button to find the answer. Area . Area of a Sector Calculator: Actually, it is very tough to remember all the formulas in the geometry class. A rectangle is a quadrilateral with four right angles. A = Area of a sector of a circle C = Central angle of a circle r = Radius of the circle In the below area of a sector of a circle calculator, enter the central angle and radius in the respective input boxes and click calculate button to find the answer. In simple terms it looks like a slice of pie. significant figures. Solution: Area of sector = 60°/360° × 25π = 13.09 cm 2. As established, the only two measurements needed to calculate the area of a sector are its angle and radius. All it needs is; the radius and angle to find the area of sector. times the fraction of the circle represented by the sector: Here’s an example: using the following figure, use the formula to find the area of sector ACB. Perimeter of an Equilateral Triangle Calculator. radius: units: angle: degrees: arc: units: chord: units: area: square units : Extra Information.
