Area of a Segment of a Circle Formula

From the below portion you can see the Area of a Segment of a Circle Formula along with the various formulae like length of segment formula, angle etc.

Length of Segment Formula

Formula:

α = 2 × cos-1(1 - (h / r))
l = r × α(radians)
s = 2 × √((2 × r × h) - (h × h))
A = (r × l / 2) - ((s) × ( r- h) / 2);


Where,
α = Angle
l = Arc length
h = Height
r = Radius
s = Chord length
A = Area
