meters

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \), where \( r \) is the radius.

Step2: Substitute the given radius

Given \( r = 4 \) meters, substitute into the formula: \( C = 2\pi(4) = 8\pi \).

Step3: Calculate the numerical value

Using \( \pi \approx 3.14159 \), we get \( C \approx 8\times3.14159 = 25.13272 \).

Step4: Round to the nearest hundredth

Rounding \( 25.13272 \) to the nearest hundredth gives \( 25.13 \).

Answer:

25.13
