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...
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...
This is the arc length formula when the angle is in degrees. The length of an arc can be calculated using different formulas, based on the unit of the central angle of the arc. The measurements of the central angle can be given indegreesorradians, and accordingly, we calculate the arc l...
What is the formula for the length of an arc? If the subtended angle is given in radians, the formula for arc length is s=r*theta, where "s" is the arc length, "r" is the radius of the circle, and "theta" is the subtended angle. If the angle is instead given in degrees, the...
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...

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.
Arc Length Formula ( if θ is in radians ) ( s ) =r Let us understand it using an example Example Calculate the length of an arc if the radius of an arc is 8 cm and the central angle is 40°. Solution We have been given that ...
The arc length is:L = θ× r (when θ is in radians)L = θ× π180× r (when θ is in degrees)Finding the Radius from Width and HeightSay you know the width and height of an arc (maybe it is on the top of a door) and you want to make that arc using some string and a...
