# Arc Length Calculator

Arc length calculator is an online calculator to determine the arc length of a circle. If the radius and angle are given we can calculate the arc length using this calculator. The equation to find out the arc length is given by,

Arc length=$\frac{n^{\circ}}{360^{\circ}}$2$\pi$ r

Where

**n**is the angle of arc

**r**is the radius of the circle
