It depends on what else is known about the sector: length of arc, area or some other measure.

radius of curvature = 2Focal length

radius = diameter/2

The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.

(arc length / (radius * 2 * pi)) * 360 = angle
