The circle is a common shape that needs to be drawn, but how can the circle be approximated with Bézier curves? The standard approach is to divide the circle into four equal sections, and fit each section to a cubic Bézier curve. This reduces the problem to a matter of fitting a cubic Bézier curve to a right circular arc.

2018-5-18 · ("Subtended" means produced by joining two lines from the end points of the arc to the center). An arc of length R where R is the radius of a circle, corresponds to an angle of 1 radian So if the circumference of a circle is 2π R i.e 2π times R, the angle for a full circle will be 2π times 1 radian or 2π radians. And 360 degrees = 2π radians


You only need to know arc length or the central angle, in degrees or radians. Area of a Sector Formula. The central angle lets you know what portion or percentage of the entire circle your sector is. A quadrant has a 90 ° central angle and is one-fourth of the whole circle. A 45 ° central angle is one-eighth of a circle.
