To use the arc length formula, you first need to know the radius of the curve and the central angle. The central angle is measured in radians and is equal to the length of the arc divided by the radius. Once you have these two values, you can plug them into the formula: arc length...
Arc length formula with degrees: Using the radian formula was faster, since the angle was in radians. 2. Find the arc length in a circle of radius 12 cm with a central angle of 1.2 radians.3. Find the length of the minor arc from point A to point B, when the radius of the circ...
If you calculate the arc length using radians, the process is a bit simpler. Since a radian value is a fraction of 2π, and we need to multiply by 2π in order to calculate the arc length, the two cancel out. We are left with this formula: Arc Length = Radian Angle x Arc Radius...

If θ is given in radians, S = θ× r Arc Length Formula Degrees If θ is given in degrees S = 2πr(θ/360) Arc Length Formula Integral Form Integral form \[S = \int_{a}^{b} \sqrt{1 + (\frac{dy}{dx})^{2} dx}\] ...
Then find the arc length using the relevant formula. Example: Calculate the arc length of a curve with sector area 25 square units and the central angle as 2 radians. We have, Sector area = 25 units Central angle = 2 radians Step 1:Sector area = 25 ⇒ (1/2) r2(2) = 25 ...
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...
In geometry, Arc is the part of circumference of a circle. It is a smooth curve with two end points. The length of the arc that subtend an angle (θ) at the center of the circle is equal 2πr(θ/360°). Learn more about arc at BYJU’S.
We find out the arc length formula when multiplying this equation by θ: L = r ×θ Hence, the arc length is equal to radius multiplied by the central angle (in radians). Area of a sector of a circle We can find the area of a sector of a circle in a similar manner. We know th...
Find Arc Length using Sector Area and Central Angle You can also find the length of the arc if the sector area and central angle are known using the formula: arc length (s) =2θ × A The arc lengthsis equal to the square root of 2 times the central angleθin radians, times the se...
