Summarizing Important Formulas of Sector of a Circle
- Formula for Area of a Sector: A = (θ/360°) × πr2
- Formula for Arc Length of a Sector: Arc Length = θ°/360° × 2πr
- Formula for Perimeter of Sector of a Circle: P = (θ/360) × 2πr + 2 × r
Sector of a Circle
Sector of a Circle is one of the components of a circle like a segment which students learn in their academic years as it is one of the important geometric shapes. The sector of a circle is a section of a circle formed by the arc and its two radii and it is produced when a section of the circle’s circumference and two radii meet at both extremities of the arc. From a slice of pizza to a region between two fan blades, we can see sectors of the circle in our daily lives everywhere.
In this article, we will explore the geometric shape of the sector which is derived from the circle in detail including its areas, perimeter, and all the formulas related to the sector of a circle.
