A circular segment is the region of a circle enclosed by an arc and a chord. It is formed when a straight line (chord) cuts through a circle, creating a curved region between the chord and the corresponding arc.
The segment's properties, such as height, arc length, and area, can be calculated using mathematical formulas based on the circle's radius and the chord length.
This calculator helps users quickly determine the key measurements of a circular segment, including arc length, perimeter, and area. By inputting at least two known values, such as the radius and height, users can compute the missing properties accurately.
It is useful for applications in geometry, engineering, and real-world scenarios such as construction, design, and manufacturing.
The radius (r) is the distance from the center of the circle to any point on its circumference. It is a fundamental value used to determine other segment properties.
The height (h) of a circular segment is the perpendicular distance from the midpoint of the chord to the arc. It helps define the size of the segment.
The chord length (s) is the straight-line distance between two points on the circle's circumference. It forms the base of the circular segment.
The angle (Θ) is the central angle subtended by the segment's arc. It is measured in degrees and determines the curve of the segment.
The arc length (l) is the curved distance along the segment's arc. It depends on the circle's radius and the central angle (Θ) and is calculated using the formula:
l = r × Θ (in radians)
The perimeter (p) of the circular segment is the total length around its boundary, including both the arc length and the chord length. It is given by:
p = l + s
The area (A) of the circular segment is the region enclosed between the arc and the chord. It is determined using:
A = (r × l / 2) - (s × (r - h) / 2)
This area is useful in geometry, physics, and engineering applications.
To use the calculator, simply input at least two known values in the designated fields. You can enter the circle radius, height, chord length, or angle. The calculator will automatically compute the missing values based on the provided inputs.
Click the “Calculate” button to generate results.
The calculator requires at least two values to perform calculations. If fewer than two values are entered, an alert will prompt you to provide additional inputs.
Valid input combinations include:
Additionally, the height (h) and chord length (s) must not exceed the circle’s diameter (2r), or an error message will be displayed.
The calculator allows you to choose the number of decimal places for the results. Use the dropdown menu labeled “Round to” to select a precision level from 0 to 15 decimal places.
The default setting is 3 decimal places, but you can adjust this according to your needs.
