Thank you

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. Using \( \pi \approx 3.14 \) and a radius of 450, the calculation is:

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

So the correct response is:

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

Thus, the first option is correct:

C ≈ 2⋅3.14⋅450
