Question

define circumference​

Answer 1

the distance round a circle or something circular

Answer 2

Step-by-step explanation:

C=2πr

Circumference to diameter. You probably noticed that since diameter is twice the radius, the proportion between circumference and diameter is equal to π: C/D = 2πR / 2R = π This proportion (circumference to diameter) is the definition of the constant pi. It is used in many areas, including physics and mathematics.
