Solution

Solution Steps

Step 1: Identify the Formula for Circumference

The formula for the circumference $ C $ of a circle is given by: \[ C = 2\pi r \] where $ r $ is the radius of the circle.

Step 2: Substitute the Given Values

We are given that the radius $ r $ is 9 centimeters and $\pi \approx 3.14$. Substitute these values into the formula: \[ C = 2 \times 3.14 \times 9 \]

Step 3: Calculate the Circumference

Perform the multiplication: \[ C = 2 \times 3.14 \times 9 = 56.52 \]
