Circumference is the length of the boundary of a circle. It is the perimeter of the circle.

The formula for the Circumference of the Circle is, C=2πr \textbf{C} = 2\boldsymbol\pi \textbf{r}

Where,

C = Circumference of the circle

π\pi (pi or Pythagorean constant) = 227\frac{22}{7} or 3.14

r = radius of the circle (in m, cm, and so on)

C=2×3.14×1C = 2 \times 3.14 \times 1

C=6.28×1C = 6.28 \times 1

C=6.28C = 6.28

Therefore, Circumference of circle with radius 1 unit is 6.28 unit
