Annulus Sector Calculator

Calculations at an annulus sector (circular ring sector). An annulus sector is a cut from an annulus, which is bordered by two straight lines from its center.
Enter the angle and either both radiuses or one radius and the side length. Choose the number of decimal places, then click Calculate. Please enter angle in degrees, here you can convert angle units.

	Radius outer circle (R):			Annulus sector Base: annulus, circular sector
	Radius inner circle (r):
	Side length (s):
	Angle (Θ):
	Outer arc length (l):
	Inner arc length (m):
