How do you get the perimeter of a circle
WebArea of sector of circle = (lr)/2 = (8 × 20)/2 = 80 square units. Example 3: Find the perimeter of the sector of a circle whose radius is 8 units and a circular arc makes an angle of 30° at the center. Use π = 3.14. Solution : Given that r = 8 units, θ = 30° = 30° × (π/180°) = π/6.
