Segment area calculator

Calculator Use the calculator below to calculate the segment area given the radius and height of the segment, using the formula described above Make sure you are using the same units for both measurements. Other circle topics

Circular Segment

Sector Area = α × πr² / 2π = α × r² / 2 The same method may be used to find arc length - all you need to remember is the formula for a circle's circumference. 💡 Note that α

Area of a circle segment with calculator

!You can find the final equation for the segment of a circle area: Asegment = Asector - Aisosceles triangle = (0.5 × r² × α) - (0.5 × r² × sin (α)) = 0.5 × r² × (α – sin (α)) Formula
