The formula is given in radians. How to determine the area of a segment? (the area bounded by a chord and an arc). Example 1:Find the area of the sector of a circle with radius 8 feet formed by a central angle of 110° Example 2:Find the area of the shaded region in the circle...
area of the sector (if theta is in ‘radians’) : = s q u a r e u n i t s area of the sector (if theta is in ‘degrees’) : = s q u a r e u n i t s area of a sector calculator is a free online tool that displays the area of the sector. byju’s online area ...
The formula to find the arc length of a sector is as follows: {eq}s=r\theta {/eq}, where you would need the length of the radius between the endpoint of the arc and the center of the circle, and the angle's measure in radians. How do you find arc length with angle and radius...
How to Find the Area of a Circular Sector? We need to know two of the following three items to find the area of a circular sector: central angle (α, measured in radians or degrees), arc lengthƒ ( L), and radius ( r). We are going to use the fact that the area of the ...
Arc length of circle( l ) (minor) =( θ /360) x 2 π r = θπ r / 180 Area of the sector(minor) =( θ /360) x π r2 If the angleθis in radians, then The area of the sector=(θ/2) r2 Sector angle of a circle θ=(180 x l )/ (π r ). ...
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...
To calculate the area of a sector, a simple formula can be used. Sector Area Formula The area of a sector can be found using the formula: sector area = 1 / 2r²θ Thus, a sector’s area is equal to the radius r squared times the central angle θ in radians, divided by 2...
Area of Sector of Circle = 1/2 × r2θ, where, θ is the angle subtended at the center, given in radians, and 'r' is the radius of the circle. How to Find Radius with Arc Length and Sector Area? The radius of a circle can be calculated if we know the arc length and the sect...
Read more about this in our circumference calculator and arc length calculator. 💡 Note that α should be in radians when using the given formula. If you know your sector's central angle in degrees, multiply it first by π/180° to find its equivalent value in radians. Or you can use...
