Calculate Circle Circumference: Given Radius r=2 Units

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information
• Step 2: Apply the appropriate formula
• Step 3: Perform the necessary calculations

Now, let's work through each step:
Step 1: The problem gives us the radius of the circle, $r = 2$.
Step 2: We'll use the formula for the circumference of a circle, which is $C = 2\pi r$.
Step 3: Substituting the radius into the formula, we get $C = 2 \times \pi \times 2 = 4\pi$.
Assuming $\pi$ is approximately 3.14, we calculate $C = 4 \times 3.14 = 12.56$.

Therefore, the circumference of the circle is $12.56$.
