Area of a Sector of Circle = 1/2 × r 2 θ, where, θ is the sector angle subtended by the arc at the center, in radians, and 'r' is the radius of the circle. Area of Sector Formula Derivation. Let us apply the unitary method to derive the formula for the area of the sector of a circle. We know that a complete circle measures 360º.
What is the Formula for the Area of a Sector of a Circle? To calculate the area of a sector of a circle we have to multiply the central angle by the radius squared, and divide it by 2. Area of a sector of a circle = (θ × r 2 )/2 where θ is measured in radians.
So if a sector of any circle of radius r measures θ, area of the sector can be given by: Area of sector = \(\begin{array}{l}\frac{\theta }{360} \times \pi r^{2}\end{array} \)
The area of a sector is the area of the region enclosed by an arc and two radii of a circle. It represents a part of the area of a circle. Area of a sector is measured in square units, depending on the unit of the radius.
In geometry you learned that the area of a circle of radius \(r \) is \(\pi r^2 \). We will now learn how to find the area of a sector of a circle. A sector is the region bounded by a central angle and its intercepted arc, such as the shaded region in Figure 4.3.1.
