This arc length calculator is a tool that can calculate the length of an arc and the area of a circle sector. This article explains the arc length formula in detail and provides you with step-by-step instructions on how to find the arc length. You will also learn the equation for sector area.
This calculator calculates for the radius, length, width or chord, height or sagitta, apothem, angle, and area of an arc or circle segment given any two inputs. Please enter any two values and leave the values to be calculated blank.
Find the length of an arc, using the chord length and arc angle. Compute the arc angle by inserting the values of the arc length and radius. This calculator uses the following formulas: Radius = Diameter / 2. Arc length = 2 × π × Radius × (Central Angle [degrees] / 360) Chord length = 2 × Radius × sin (Central Angle [degrees] / 2)
Once you've entered the angle and radius, click the "Calculate Arc Length" button on the calculator. Our Arc Length Calculator will then display the length of the arc of the circle. L = (θ/360) * 2 * π * r
Find the arc length of a sector by entering the central angle and radius in the calculator below. Arc length is a measurement of distance along the circumference of a circle or sector between two points. Put another way, an arc is the curved outer edge, or circular portion, of a sector.
The simple arc length calculator finds the arc length, the radius, and the sector area of a circle. Learn formulas to solve arc length problems instantly!
This online calculator computes the arc length of a circular segment, given either the radius and angle of the segment, or the chord length and the height of the segment, or the radius and the height of the segment.
