Multiply the area squared minus the radius
The circumference is the distance around a closed curve. It is used to mean the perimeter of a circle.The circumference is the distance around a closed curve (i.e. a circle).
Technically, yes.
An ELLIPSE.
circle
simple curve is a curve which doesnot cross itself,it neednot be closed....... but a simple closed curve is a curve which is simple and also closed. every simple closed curve is a simple curve but not vice versa.
Multiply the area squared minus the radius
By integration. Divide the curve into small pieces, then add up the length of all the pieces.
x(t)=t^2 , y(t)=t^3-t is a non-simple curve.

The circumference is the distance around a closed curve. Circumference is a special perimeter.

yes but the figure is a closed curve. The distance around an object is the perimeter.
No, it is not.
