How do you find the area of a sector segment and a circle?
Area of a Sector of Circle = (θ/360º) × πr2, where, θ is the angle subtended at the center, in degrees, and r is the radius of the circle. Area of a Sector of Circle = 1/2 × r2θ, where, θ is the angle subtended at the center, in radians, and r is the radius of the circle.
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 × r2 )/2 where θ is measured in radians. The formula can also be represented as Sector Area = (θ/360°) × πr2, where θ is measured in degrees.
What is sector and segment in circle?
A sector is the part of a circle enclosed by two radii of a circle and their intercepted arc. The segment of a circle is the region bounded by a chord and the arc subtended by the chord.
What is the perimeter of a sector of a circle?
Perimeter of sector = 2 radius + arc length. Arc length is calculated using the relation : Arc length = l = (θ/360) × 2πr. Therefore, Perimeter of a Sector = 2 Radius + ((θ/360) × 2πr )
What is segment circle?
Segment (of a Circle) Segment (of a Circle) A segment is a region bounded by a chord of a circle and the intercepted arc of the circle. A segment with an intercepted arc less than a semicircle is called a minor segment. A sector with an intercepted arc greater than a semi-circle is called a major segment.

How do you calculate the perimeter of a sector?
Perimeter of a sector-Formula
- So the formula for the perimeter of sector will be: 2r + (θ/360)*2πr = 2r[1 + (θ*π)/180]
- The range of value of the perimeter of a sector: 2r(2r + 2πr).
- A circle with a radius of 10 m has a sector making an angle of 60° at the center.
How do you find the sector of a circle?
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, π × r 2, by the fraction x /360, where x is the measure of the central angle formed by the two radii.
What is the equation for the sector of a circle?
A Circular Sector is portion of circle enclosed by two radii and an arc. The formula used to calculate the area of the circular Sector is, Formula. Sector Area = (π r2 θ) / 360. Where, A is the Area of the circular sector.
What is the difference between a segment and a sector?
sector | segment | Related terms |. is that sector is (geometry) a part of a circle, extending to the center while segment is (geometry) the part of a circle between its circumference and a chord (usually other than the diameter).
What is the section of a circle?
A circular sector or circle sector (symbol: ⌔), 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.
