Arc Length Calculator computes the length of the arc by using different formulas depending upon the unit of the specified central angle. The central angle can be expressed in either degrees or radians. To use the arc length calculator, enter the values in the given input boxes....
Thus, the length of an arc is equal to the radiusrof the sector times the central angle in radians. Note that the central angle must be in radians, not degrees, because the units must be the same on both sides of the equation.
(You can also input the diameter into the arc length calculator instead.) What will be the angle between the ends of the arc? Let's say it is equal to 45 degrees, or π/4. Calculate the arc length according to the formula above: L = r ×θ = 15 ×π/4 = 11.78 cm Calculate ...
In particular, the length of an arc of a circle of radius 'r' that subtends an angle θ at the center is calculated by the formula rθ × (π/180) if the angle is in degrees and if the angle is in radians, then the arc length is rθ. Let 's see how to derive these formula...

Arc Sine Calculator You can enter input as either a decimal or as the opposite overthe hypotenuse There are 2 different ways that you can enter input into oursin−1sin−1calculator. Method 1: Enter a decimal between -1 and 1 inclusive. Remember that you cannot have a number greater ...
For example, when determining the length of an arc for a given angle, we use the formula above, rearranged to be s = θr. If θ is in radians and r is in meters, then the units of s will be meters, not radian-meters. If θ were in degrees, however, then s would have units ...
