The circumference \( C \) of a circle can be calculated using the formula:
\[
C = 2\pi r
\]
where \( r \) is the radius of the circle. Given that the radius \( r \) is 17 mm, we can substitute this value into the formula:
\[
C = 2\pi \times 17 = 34\pi \text{ mm}
\]
Therefore, the exact circumference of the circle is \( 34\pi \) mm.
So, the correct response is:
**34π mm** (or 34 pi mm).
\[
C = 2\pi r
\]
where \( r \) is the radius of the circle. Given that the radius \( r \) is 17 mm, we can substitute this value into the formula:
\[
C = 2\pi \times 17 = 34\pi \text{ mm}
\]
Therefore, the exact circumference of the circle is \( 34\pi \) mm.
So, the correct response is:
**34π mm** (or 34 pi mm).
