The calculator is powerful and easy to use, Click on the two variables you know:

Radius & Segment Height ED Radius & Apothem OE

Radius and Central Angle Radius & Chord AB

Radius & Arc ADB

Chord AB & Segment Height ED Chord AB & Apothem OE

Segment Height ED & Apothem OE Chord AB & Arc ADB












 

Significant Figures >>>  

Las líneas OA y OB son el radio del círculo.

Lines AB es un acorde del círculo.

El ángulo AOB es un ángulo central.

La línea OE es el apotem.

La línea curva ADB es arco del círculo.

El área de un segmento es igual a la zona del sector - Triángulo AOB Área

Línea Ed es la altura del segmento.

El área AOBD es un sector.

Longitud del arco adb = (ángulo central / 180 °) * π * r

Área del sector AOBD = (ángulo AOB / 360 °) * π * R²

El área de ADBD es el segmento.
