Circumference of circle with radius 50 units

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, $\textbf{C} = 2\boldsymbol\pi \textbf{r}$

Where,

C = Circumference of the circle

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

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

$C = 2 \times 3.14 \times 50$

$C = 6.28 \times 50$

$C = 314$

Therefore, Circumference of circle with radius 50 unit is 314 unit
