Step-by-step explanation:

Length of the Arc of Sector Formula

For the radius of a circle equal to r units, an arc of length r units will subtend 1 radian at the centre. Hence, it can be concluded that an arc of length l will subtend l/r, the angle at the centre. ... θ = l/r, where θ is in radians.
