distance around a circle
The distance all the way around a circle or round object.
Használati minta:
the circumference of [something]
Gyakori hiba:
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'.
Szinonimák
perimeter (A general word for the distance around any shape, not only circles; often used in everyday contexts more than in strict geometry for circles.)
|
girth (Usually refers to the distance around the body of a person or animal, especially around the waist or chest; more physical and concrete than the mathematical term.)
Antonimák
diameter (A contrasting measurement that goes straight across a circle through its center, instead of around it.)

The outside edge or line around a round area or round object.
Használati minta:
around the circumference of [something]
Gyakori hiba:
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.
Szinonimák
edge (A more general and common word for the outer limit of a surface or area, not limited to round shapes.)
|
border (Emphasizes the dividing line between two areas; not limited to circular shapes and used more broadly in geography and design.)
Antonimák
center (Refers to the middle point of a space or object, in contrast to its outer boundary.)
