Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given diameter into the formula

Given that the diameter \( d = 9 \) inches and using \( \pi\approx3.14 \), we substitute into the formula: \( C = 3.14\times9 \)

Step3: Calculate the result

\( 3.14\times9 = 28.26 \) inches.

Answer:

28.26 inches (corresponding to the option with "28.26 inches")
