Circular segment
Can calculate area, arc length,chord length, height and perimeter of circular segment by radius and angle.
Circular segment - is an area of a "cut off" circle from the rest of the circle by a secant (chord).
On the picture:
L - arc length
h- height
c- chord
R- radius
a- angle
If you know radius and angle, you may use the following formulas to calculate the remaining segment parameters:

Circular segment
But if you don't know radius and angle, you still can calculate the segment parameters by chord length and segment height:
Segment defined by chord and height
Formula for segment radius by chord and height:
Then, you can caluclate segment angle using the following formula:
You may also use the following calculator to obtain segment area by its radius and height:
Area of circle segment by radius and height
This calculator evaluates angle by the following formula:
then it uses formula [1] to calculate the segment area.
