$\sf\large\underline{Given:-}$

$\rightarrow$ Radius(r) of the circle = 2 ft.

$\rightarrow$ Value of Pie(π) = 3.14

$\sf\large\underline{To\: Find:-}$

$\rightarrow$ Circumference of the circle.

$\sf\large\underline{Formula \: Used:-}$

$\rightarrow$ Circumference of circle =
$\sf{2πr}$

$\sf\large\underline{Solution:-}$

$\rightarrow$ Circumference of circle =
$\sf{2πr}$ (putting the value of π and r from the above given)

$\rightarrow$
$\sf{=2×3.14×2}$

$\rightarrow$
$\sf{=12.56\: ft.}$

Therefore, circumference of the given circle =
$\sf{12.56\: ft.}$

Given -

ps - use 3.14 for π

To find -

Solution -

We know to find the circumference of a circle we use the formula C=2πr.

Doing the same,

C = 2 × 3.14 × 2

C = 12.56 feet
