Solution Steps

Step 1: Start with the equation for the circumference of a circle

Given the general form of the equation is \(C = 2\pi r\), where \(C\) is the circumference and \(r\) is the radius. In our case, \(C = 2\).

Step 2: Isolate the radius (\(r\))

To find the radius, we rearrange the equation to solve for \(r\). This gives us \(r = \frac{C}{2\pi}\).

Step 3: Substitute the values and calculate

Substituting the given values, we get \(r = \frac{2}{2 \times 3.142}\). After calculation, \(r ≈ 0.32\) (rounded to 2 decimal places).

Final Answer:

The radius of the circle, rounded to 2 decimal places, is approximately 0.32.
