To find the diameter of a circle from its circumference, you can use the formula:
\[ C = \pi \times d \]
where \(C\) is the circumference and \(d\) is the diameter. Rearranging the formula to find the diameter gives:
\[ d = \frac{C}{\pi} \]
Substituting the given values:
\[ d = \frac{574}{3.14} \]
Now, let's calculate the diameter:
\[ d \approx \frac{574}{3.14} \approx 183.3 \]
Rounding to the nearest tenth, the diameter is approximately \(183.3\) meters.
If your answer isn't \(183.4\), it may be due to rounding conventions or the values used for \(\pi\). In this case, rounding \(183.3\) yields \(183.3\) as the proper rounded figure.
