### What is Meant by Arc of a Circle?

In Geometry, the set of all points in a plane which are equally spaced from a fixed point is known as a circle. The perimeter of the circle is known as its circumference. A chord of a circle is the line segment joining any two points on the circumference of a circle. An arc of a circle is a part of the circumference. Arc is a continuous piece of the circle. The length of an arc of a circle which subtends an angle of ‘θ’ (in degrees) and has a radius of ‘r’ units is given as:

Arc length = 2πr × (θ/360°)

To find the length of the arc of any circle, simply input the radius and the angle subtended by it at the centre in degrees.
