This calculator finds the area of a sector when the radius (or diameter) and the angle are known. Type the angle you want for the sector, and choose whether to use degrees (default) or radians. Select if you want to use the radius or diameter (default is radius). ...
Learn how to use the area of a sector calculator with a step-by-step procedure. Get the area of a sector calculator available online for free only at BYJU'S.
To calculate the area of a sector, a simple formula can be used. 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 th...
The radius can be expressed as either degrees or radians, with our area of a sector calculator accepting only degrees for now (let us know if it would help you if it supported radians as well). π is, of course, the mathematical constant equal to about 3.14159. Area of a Sector ...
Calculate the area of a sector, formula in degrees and radians, area of segment, how to calculate the central angle of a sector, how to calculate the radius of a sector, in video lessons with examples and step-by-step solutions.
Area of a Sector of Circle = 1/2 × r2θ, where, θ is the sector angle subtended by the arc at the center, in radians, and 'r' is the radius of the circle. Area of Sector Formula Derivation Let us apply theunitary methodto derive the formula for the area of the sector of a ...
The arc length s of a segment is equal to the radius r times the central angle θ in radians. Again, as with most of the above equations, the central angle must be in radians, not degrees. You might also be interested in our sector area calculator for solving the parts of a sector...
It is defined as the angle subtended by an arc of a circle that has the same length as the circle's radius. How do you convert degrees to radians? To convert degrees to radians, you can use the formula radians = (degrees * π) / 180. Alternatively, you can use...
Perimeter of a sector calculator Quarter circle calculator Quarter circle perimeter calculator How to calculate the arc of a quarter circle? The arc of a quarter circle equals 1/4 of a perimeter of the entire circle. If we want to calculate it, we need to divide the mentioned parameter by ...
. And sector of a circle AOB. Arc length of circle( l ) (minor) = ( θ /360) x 2 π r = θπ r / 180 Area of the sector (minor) = ( θ /360) x π r 2 If the angle θ is in radians, then The area of the sector = (θ/2) r 2 Sector angle of a circle θ ...
