Convert the diameter of the can from millimeters to centimeters.

Step 1: Convert the diameter of the can from millimeters to centimeters.
The diameter is given as $73 \text{ mm}$.

$$\text{Diameter} = 73 \text{ mm} = \frac{73}{10} \text{ cm} = 7.3 \text{ cm}$$

Step 2: Calculate the circumference of the can using the given formula.

$$\text{Circumference} = \text{diameter} \times 3.142$$ $$\text{Circumference} = 7.3 \text{ cm} \times 3.142$$ $$$$
