How To Find Area Of A Circle Sector. Find the area of the sector of a circle of radius 12 km with a central angle of 210°. Typically, the formula to calculate the area of a sector of a circle is a = pi *r 2.

The formula for area, a , of a circle with radius, r , and arc length, l , is: In this video i will show you how to find the area of a sector when using the area of a circle formula.we will use the angle given and the amount of degrees. Area of sector = θ 2 × r 2 (when θ is in radians) area of sector = θ × π 360 × r 2 (when θ is in degrees) area of segment.

### The Formula To Calculate The Sector Area Is:

Area of sector = 25 × 3.14 / 6 = 13.08 sq. In this video i will show you how to find the area of a sector when using the area of a circle formula.we will use the angle given and the amount of degrees. Therefore the circle will be divided into 8 parts, as per the given in the below figure;

### Thus The Area Of A Sector Is Calculated As:

The area of a segment is the area of a sector minus the triangular piece (shown in light blue here). There is a lengthy reason, but the result is a slight modification of the sector formula: The arc length of the sector of radius r can be calculated with the formula, arc length of a sector = r × θ ☛ related articles.

### Typically, The Formula To Calculate The Area Of A Sector Of A Circle Is A = Pi *R 2.

To calculate the sector area, first calculate what fraction of a full turn the angle is. Area of sector = $$\frac{\theta }{360} \times \pi r^{2}$$ derivation: 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.

### The Formula Used To Calculate The Area Of A Sector Of A Circle Is:

The area of a sector of a circle with radius 'r' is calculated with the formula, area of a sector = (θ/360º) × π r 2; In a circle with radius r and center at o, let ∠poq = θ (in degrees) be the angle of the sector. The figure below illustrates the measurement:

### Area Of A Sector Of A Circle = (Θ × R 2 )/2 Where Θ Is Measured In Radians.

The area of a sector of a circle is the fractional area of the circle. Watch this video to know more about perimeter of a circle, area of a sector of a circle, area of a circle, and volume.to learn more about perimeter and area,. $$\text{sector area} = \frac{\text{angle}}{360} \times \pi r^2$$
