feet

Explanation:

Step1: Recall circumference formula

The formula for the circumference \( C \) of a circle is \( C = \pi d \), where \( d \) is the diameter.

Step2: Substitute the diameter value

Given \( d = 4 \) feet, substitute into the formula: \( C=\pi\times4 = 4\pi \).

Step3: Calculate the numerical value

Using \( \pi\approx3.14159 \), we get \( C\approx4\times3.14159 = 12.56636 \).

Step4: Round to nearest hundredth

Rounding \( 12.56636 \) to the nearest hundredth gives \( 12.57 \).

Answer:

12.57
