Circular Sector
Where r is the radius of the circle, c is the chord length, s the arc length, h the height of the arced portion, m is the height of the triangular portion, and θ is the central angle with θ < π radians (180°).
Circular Segment
Where r is the radius of the circle, c is the chord length, s the arc length, h the height of the arced portion, m is the height of the triangular portion, and θ is the central angle with θ < π radians (180°).
Where a and b are the lengths of adjacent sides and h is the height perpendicular to base a.
Where n is the number of sides and a is the length of each side (regular polygon).
