Answer 1

The correct formula to find the approximate circumference of a circle is:

\[ C \approx 2 \cdot \pi \cdot r \]

where \( r \) is the radius of the circle.

Given that the radius is 450, we can substitute this value into the formula:

\[ C \approx 2 \cdot 3.14 \cdot 450 \]

So, the correct response from your options is:

C ≈ 2 ⋅ 3.14 ⋅ 450.
