3 days ago · 2π → πr². So, what's the area for the sector of a circle: α → Sector Area. From the proportion, we can easily find the final sector area formula: Sector Area = α × πr² / 2π = α × r² / 2. The same method may be used to find arc length – all you need to remember is the formula for a circle's circumference.
- The sector of a circle is a slice of a circle, bound by two radiuses and an arc of the circumference. We identify sectors of a circle using their c...

The area of a sector of a circle is the amount of space occupied within the boundary of a sector of a circle. A sector always initiates from the center of the circle. The semi-circle is also a sector of a circle, in this case, a circle is having two sectors of equal size. Let's learn about how to calculate the area of a sector. If the radius of the...
Similarly, the length of the arc of the sector with angle θ is given by; l = (θ/360) × 2πr or l = (θπr) /180. Area of a Sector of a Circle Without an Angle Formula When the angle of the sector is not given and the length of the arc of a sector of a circle is given we can calculate the area of the sector of a circle by using length. Assuming the len...
The following are the formulas for the perimeter of a sector of a circle. Perimeter of sector = 2 radius + arc length Arc length is calculated as, Arc length = l = (θ/360) × 2πr Therefore, Perimeter of a Sector = 2 Radius + ((θ/360) × 2πr )

This calculator and formula make it easy to find the area of your circle sector. Circle Sector Area Formula. The formula for finding the area of a circle sector is: S = \pi *R^2* \dfrac {\alpha^o} {360^o} S = π ∗ R2 ∗ 360oαo. Where S is the area, α is the central angle of the sector in degrees, π is pi (3.14), and R is the radius of the circle.
A sector is a pie-slice-shaped portion of a circle where its straight edges are two radii of the circle, and the outer curve portion of the circle’s outer arc. A defining characteristic of a sector is its central angle, denoted as θ (Greek letter theta).
Area of sector = θ 360 ∘ × π r 2. If is measured in radians, then “the area of a sector of a circle formula” is given by. Area of sector = 1 2 × θ × r 2. Perimeter of sector = 2 r + θ 360 × 2 π r.
