All it needs is; the radius and angle to find the area of sector. Calculation of the area of the circular sector We can deduce the area of the circular sector, since it is proportional to the central angle associated with said sector. Area . angle Î¸ 0: degree radian; angle Î¸ 1: same unit as Î¸ 0; semimajor axis a: semiminor axis b: area of sector S . Circular segment. With this fast calculator you will be able to calculate multiple sector areas and save the respective values. radius: units: angle: degrees: arc: units: chord: units: area: square units : Extra Information. This handy tool displays the sector area of a circle within seconds. Questionnaire. FAQ. How to Find the Arc Length. Use your calculator value of r. 8 in. Digits after the decimal point: 2. significant figures. Write a Python program to calculate the area of a sector. The angle between the two radii is called as the angle of surface and is used to find the radius of the sector. FAQ. Whether you want to calculate the Area (A), Arc (s), or one of the other properties of a sector including Radius (r) and the Angle formed, then provide two values of input. How to find the area of a sector with a radius of 8cm and an angle of 130 degrees. You can use the sector area calculator to find the area of a sector: Enter the radius of your sector. In simple terms it looks like a slice of pie. Calculate The Area Of A Sector (Using Formula In Degrees) We can calculate the area of the sector, given the central angle and radius of circle. The area of a sector of a circle is ½ r² â, where r is the radius and â the angle in radians subtended by the arc at the centre of the circle. About Area of A Sector Calculator . On the picture: L - arc length h- height c- chord R- radius a- angle. See the video below for more information on how to convert radians and degrees Sector area formula. Calculation precision.
