The circumference of a circle can be calculated using the formula:

\[ C = \pi \times d \]

where \( C \) is the circumference and \( d \) is the diameter of the circle.

Given that the diameter of the circle is 16 inches, we can substitute this value into the formula:

\[ C = \pi \times 16 \]

This simplifies to:

\[ C = 16\pi \]

So, the exact circumference of the circle is **16π in.**
