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 \( r = 14 \) feet, substitute into the formula: \( C = 2\times\pi\times14 \).

Step3: Calculate the value

First, simplify \( 2\times14 = 28 \), so \( C = 28\pi \). Using \( \pi \approx 3.14159 \), we get \( C \approx 28\times3.14159 \). Calculate \( 28\times3.14159 = 87.96452 \).

Step4: Round to the nearest hundredth

Rounding \( 87.96452 \) to the nearest hundredth gives \( 87.96 \).

Answer:

87.96
