○ 25.13 in
○ 50.27 in
○ 45.00 in
○ 100.53 in

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given diameter

Given $d = 16$ inches and taking $\pi\approx3.14159$. Then $C=\pi\times16 = 3.14159\times16$.

Step3: Calculate the result

$3.14159\times16=50.26544$ inches.

Step4: Round to the nearest hundredth

Rounding $50.26544$ to the nearest hundredth gives $50.27$ inches.

Answer:

50.27 in
