Are circumference and circle the same thing? Many students confuse circumference with circle, after this class you will never be confused again. Circumference is a subject of plane geometry studied in the 7th grade, 8th grade or 9th grade, depending on the organization of the content in each school. In this class you will learn the elements of the circumference (chord, radius and diameter), how to calculate the length of the circumference (also known as the perimeter of the circumference) and how to solve circumference problems.
