#### 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
Use this **online Length of Segment Calculator** to calculate the area of partial circles using the height and the radius within the blink of eyes.

**Height:** It is defined as the height from the center of the circle to the highest point in the partial circle.

**Radius:** The radius refers to the distance from the center of the circle to the lowermost point of the partial circle which meets circumference of the outer circle.

**Length of Segment Calculator :** This is a simple online measurements calculator to find the area of the partial circle using the height and radius of the circle. Save your time and know the area of the circles in just seconds using this **online Area of a segment of a circle calculator**.
