Circle, sector, segment, string and arc length, area online formula calculator Lines AO and OB are called radii. Lines AC, BC and AB are called strings. The angle ABC is an inscribed corner. The angle AOB is the central angle.
Arcs are an important aspect of geometry, physics, trigonometry and design work. However, curved lines are much more difficult to measure than straight lines, which is why it's important to familiarize yourself with the arc length formula.

Arc length formula: \(l=(nπr)/180\) or \(l=n/180·πr\) or \(l=|α|r\) n is the number of center angles, r is the radius, *α is the central angle of the arc. In a circle with a radius R, since the arc length of the 360° center angle is equal to the circumfere...
A=12r2θwhere againis the radius of the circle andθis the subtended angle in radians. If the subtended angle and sector area are known, this equation can be rearranged to find the radius, yielding the expression r=2AθOnce the radius has been calculated, the arc length can be found usi...
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...
