Use

3.14

for

\pi

. If necessary, round your answer to the nearest hundredth.

\newline

_____ centimeters

Identify formula: Step $1$ : Identify the formula for the circumference of a circle, which is $C = 2\pi r$ . Here, $r$ is the radius of the circle.
Perform multiplication: Step $2$ : Perform the multiplication to find the circumference. $\newline$ Calculation: $C = 2 \times 3.14 \times 3 = 18.84 \text{ cm}$
