Frequently Asked Questions
What is the formula for the perimeter of a sector?
The perimeter equals twice the radius, for the two straight edges, plus the arc length, the central angle in radians times the radius.
What is the perimeter of a sector with a 10 unit radius and a 60 degree angle?
A sector with a radius of 10 and a central angle of 60 degrees has a perimeter of about 30.47 units.
How is this different from the sector area calculator?
This tool focuses only on the boundary length of the sector, while the sector area calculator also finds the enclosed area and the chord length.
