Your ratios of lengths and areas description is true for plane figures that are similar to each other, in the sense of being the same shape but possibly different
θ = central angle in degrees. The area of the shaded sector can be determined using the formula StartFraction measure of angle Z Y X Over 360 degrees EndFraction (pi r squared). Which best explains the formula? The central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector. Note the number of square units it takes to fill it and the calculation. If you know the radius of the circle and the height of the segment, you can find the segment area from the formula below.

Area of the circular region is πr². Let this region be a sector forming an angle of 360° at the centre O. Then, the area of a sector of circle formula is calculated using the unitary method. 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. In the diagram, θ is the central angle, r {\displaystyle r} the radius of the circle, and L {\displaystyle L} is the arc length of the minor sector. A sector with the central angle of 180° is called a half-disk and is bounded by a diameter and a semicircle. Sectors with other central angles are sometimes So, what's the area for the sector of a circle: α → Sector Area.

Area of a Sector A sector in a circle is the region bound by two radii and the circle. Since it is a fractional part of the circle, the area of any sector is found by multiplying the area of the circle, pi × r 2, by the fraction x/360, where x is the measure of the central angle formed by the two radii. This video explains the definition of a sector and how to find the sector area of a circle.
