Radius Angle Arc Chord Area of A Sector Calculator
Significant figures:
A sector ia a part of a circle. It has two lines and a arc forms the circumference of it. If the angle of the sector is 180 degrees the sector is a semi-circle, the angle of the sector is 360 degrees then the sector is a circle.
Radius Angle Arc Chord Area of A Sector formula
perimeter = radius + radius + arc
Radius r = (c² / 8h) + (h / 2)
Where C is the chord length, h is the height between the chord and arc.
Area S = arc * radius / 2
