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.**
\[ C = \pi \times d \]
where \( C \) is the circumference and \( d \) is the diameter of the circle.
