To find the circumference of a circle, you can use the formula:
\[ C = 2 \pi r \]
where \( C \) is the circumference, \( \pi \) is approximately 3.14, and \( r \) is the radius of the circle.
Given that the radius \( r \) is 5.5 cm, we can calculate the circumference as follows:
\[ C = 2 \times 3.14 \times 5.5 \]
Calculating this:
\[ C = 2 \times 3.14 \times 5.5 = 34.54 , \text{cm} \]
So, the circumference of the circle is approximately:
\[ \text{Circumference} = 34.54 , \text{cm} \]
Rounded to the nearest hundredth, the final answer is:
34.54 cm.
