The areaRadial.outerRadius() method is used to set or return the outerRadius accessor of the areaRadial. It can be a number or a function that returns a number representing the outerRadius of our areaRadial.
Syntax:
areaRadial.outerRadius(outer_Rad);
Parameters: This method accepts single parameter as mentioned above and described below:
- outer_Rad: This parameter holds the outerRadius that can be a number or a function returning the outerRadius.
Return Value: This method returns the outerRadius accessor function of the area radial.
