To calculate the circumference \( C \) of a circle, you can use the formula:
\[ C = 2 \pi r \]
where \( r \) is the radius of the circle. Given that the radius \( r \) is 5 centimeters and using \( \pi \approx 3.14 \):
\[ C = 2 \times 3.14 \times 5 \]
Now, calculating that:
\[ C = 2 \times 3.14 = 6.28 \] \[ C = 6.28 \times 5 = 31.4 \text{ centimeters} \]
So, the circumference of the plate is 31.4 centimeters.
