Arc length is the distance along the curved line of an arc. It is measured in units such as inches, centimeters, or degrees.
The formula for calculating arc length is: s = rθ, where s is the arc length, r is the radius of the arc, and θ is the central angle in radians.
Arc length is a measurement of the actual distance along the arc, while arc measure is the size of the central angle in degrees or radians.
No, arc length cannot be negative as it is a measurement of distance and distance cannot be negative.
Arc length is important in geometry as it is used to measure the length of curves, such as circles, and to calculate various properties of these curves, such as area and circumference.
