What is a Sector Perimeter?
The perimeter of a sector is the length of its entire boundary. This consists of the curved arc length plus the two straight radii that connect the arc to the center of the circle.

Pro Tips
If the angle is in degrees, arc length L = (θ/360) * 2πr.
If the angle is in radians, arc length L = rθ.
The perimeter of a full circle (θ = 360°) is just the circumference 2πr.

Fun Facts
"A slice of pizza is roughly a sector, and its perimeter would be the sum of its two straight sides and its crust."
