How do you find the perimater of a sector?

Answer 1

To find the perimeter of a sector, you need to calculate the lengths of the two radii and the arc length of the sector. The formula for the arc length is ( L = \frac{\theta}{360} \times 2\pi r ), where ( r ) is the radius and ( \theta ) is the central angle in degrees. The perimeter ( P ) of the sector is then given by ( P = 2r + L ). Thus, you combine the lengths of the two radii with the arc length to get the total perimeter.
