In this formula, 'θ' represents the central angle of the sector, measured in degrees, 'π' (pi) is the mathematical constant approximately equal to 3.14159, and 'r' represents the radius of the circle.
To calculate the area of a sector, you need to know the central angle in degrees and the radius of the circle.
For example, let's consider a sector with a central angle of 60 degrees and a radius of 8 meters:
Area = (60/360) × Ï€ × (8 meters)^2 Area = (1/6) × 3.14159 × 64 square meters Area ≈ 33.51 square meters
In this case, the area of the sector is approximately 33.51 square meters.
Sectors have several properties:
The central angle represents the fraction of the entire circle that the sector encompasses. It is measured in degrees and can range from 0 degrees (a degenerate sector, which is just a single point) to 360 degrees (a full circle).
The length of the arc that forms the sector is proportional to the central angle. The formula to calculate the length of the arc is: Arc Length = (θ/360) × 2Ï€r, where 'r' represents the radius.
The central angle of a sector and the corresponding arc length together determine the area of the sector.
Sectors are often encountered in various fields, including geometry, physics, and engineering. They have practical applications in areas such as pie charts, angular measurements, and calculations involving circular motion or angles.

The major axis is the longest diameter of the ellipse, while the minor axis is the shortest diameter. The midpoint of the major axis is the center of the ellipse.
Calculating the area of an ellipse requires the knowledge of its semi-major axis (a) and semi-minor axis (b). The formula for the area of an ellipse is:
Area of an Ellipse = Ï€ × a × b
In this formula, π (pi) is a mathematical constant approximately equal to 3.14159, and 'a' and 'b' represent the lengths of the semi-major and semi-minor axes, respectively.
For example, let's consider an ellipse with a semi-major axis of 6 meters and a semi-minor axis of 4 meters:
Area = Ï€ × 6 meters × 4 meters Area ≈ 75.3982 square meters
In this case, the area of the ellipse is approximately 75.3982 square meters.
Ellipses possess several noteworthy properties:The sum of the distances from any point on the ellipse to the two foci is constant.
The lengths of the major and minor axes determine the shape and orientation of the ellipse.
The eccentricity of an ellipse, denoted by 'e', measures its elongation or deviation from a circle. It is calculated as the distance between the center and one of the foci divided by the semi-major axis.
Ellipses find applications in various fields, including physics, astronomy, engineering, and architecture. They are commonly used to describe the orbits of celestial bodies, the shape of lenses and mirrors, and the design of structures such as bridges and arches.
