Is there a technical difference between the words 'circle' and 'circumference'?
Can the word 'circle' refer indistinctly either only to the inner part the geometric figure or only to its boundary? Or even the union of both these regions? Is there another word to apply here?
I know that in Portuguese 'circle' definitely differs from 'circumference', we talk about the area of a circle and about the perimeter of a circumference. And in English, does such distinction exist?

In AmE - a circle is a geometric shape. The circumference is the length of the perimeter of that shape.
The area is the space contained inside the circle.
Circle is the shape.
Circumference is the length of the perimeter of the shape.
Yes - big difference.
