Learn about the formulas associated with the sector of a circle. Discover the definition of a sector and how to use both the arc length and sector area formulas. Updated: 11/21/2023 Table of Contents What is a Sector of a Circle? Sector of a Circle Area Formula Sector of a Circle ...
If we need to find the area of sector when the angle is given in radians, we use the formula, Area of sector = (1/2) × r2θ; where θ is the angle subtended at the center, given in radians, and 'r' is the radius of the circle. So, let us understand where the formula comes...
The sector that is being referred to is a sector of a circle. What is the Formula for the Area of a Circular Sector Using Radians? Again, to solve for the area, the central angle and radius must be known. The procedure is similar to what we did in the previous section. We have ...

In summary, the formula to find the area of a sector in a circle is A = (πr^2θ)/360, where θ is the central angle in degrees. If θ is in radians, the formula becomes A = (r^2θ)/2. The sector area is simply a fraction of the total area of the circle. ...
To find the area of a sector of a circle, use this formula:The area of a sector \(=πr^2 (\frac{θ}{360})\), \(r\) is the radius of the circle, and \(θ\) is the central angle of the sector.To find the arc of a sector of a circle, use this formula:Arc of a ...
The Semi-circle of any circle can also be considered a sector. In that scenario, however, a circle will be said to have two sectors where both sectors will possess the same amount of area. Now let us get familiar with the formula for determining the total area of a sector. Let us ...
Circle Area = π× r2 r = radius Ellipse Area = πab Sector Area = ½ × r2×θ r = radiusθ = angle in radians Note: h is at right angles to b Example: What is the area of this rectangle? The formula is: Area = w × h w = width h = height We know w = 5 an...
What is Sector Area Calculator A Sector Area Calculator is a tool that helps to calculate the area of a sector, which is a part of a circle enclosed between two radii and an arc of the circle. The formula to calculate the area of a sector is given by: A = (θ/360) x πr^2 wh...
Sector Area Formula Theareaof a sector can be found using the formula: sector area =1/2r²θ Thus, a sector’s area is equal to the radiusrsquared times the central angleθin radians, divided by 2. If you know the diameter of the circle, you can find the radius by dividing the ...
