WebThis question asks you to investigate a circle inscribed in a sector that is inscribed in another circle. r = radius of small circle L = radius of sector R = radius of big circle … WebThe formula for the perimeter of the sector of a circle is given below : Perimeter of sector = radius + radius + arc length. Perimeter of sector = 2 radius + arc length. Arc length is calculated using the relation : Arc length = l = (θ/360) × 2πr. Therefore, Perimeter of a Sector = 2 Radius + ((θ/360) × 2πr )
