WebFeb 23, 2024 · The formula for the perimeter of a sector is 2r [1 + (θ*π)/180]. The maximum possible value θ can reach is 360 o. But at θ = 360, there will be no sector, it will be a complete circle. So θ can attain any value less than 360. At 360 the value of perimeter of the sector will become 2r + 2πr.
