Typisk fejl:
Learners often confuse 'circumference' with 'radius', 'diameter', or 'perimeter'. 'Circumference' is the distance around a circle. The radius is the distance from the center to the edge, the diameter is the distance across the circle through the center, and 'perimeter' is the distance around any shape (not just a circle). Another common mistake is to say 'a circumference of the circle is 10 cm'; more natural is 'the circumference of the circle is 10 cm'.

Typisk fejl:
Learners may think 'circumference' in this sense must always involve numbers or measurement, but it can simply mean the outer line or edge of a round area. In everyday descriptions, 'edge' or 'around the edge' is often more natural, so overusing 'circumference' in casual speech can sound too technical.
Betydning
outer boundary of a round area
