WebThe perimeter of a sector is the distance around a sector. We can calculate the perimeter of a sector by adding together the lengths of the two radii and the arc length of the sector. To find the arc length of a sector we need to use the formula, \text {Arc length } = \frac {\theta} {360} \times \pi\times d.
