Which term describes the distance around the boundary of a circle or object?

Explanation:
The distance around the boundary of a circle is called the circumference. Think of wrapping a string around the edge—the length of that string equals the circumference. It’s related to the circle’s size by C = 2πr or C = πd. The inside space of the circle is its area (A = πr^2), while compression and cycle describe other concepts not about the boundary length.
