Wanting to calculate arc length? Use our arc length of curve calculator to do so, given the radius and the angle formed by the arc.
Arc length is a measure of the distance along the curved line of a circle and is an important concept in mathematics.
Area of a Sector (A):157.1m2
The distance that separates two points along a curve section is called arc length. Curve rectification approximates an irregular arc segment as connected line segments to determine its length.
The equation for the arc length of a circle is:
The equation for the area of the sector it creates is:
Where θ is the central angle in radians and r is the radius of the circle.
