What is the circumference of a circle with radius 5? (Use π ≈ 3.14)

Explanation:
Circumference is found with C = 2πr. With radius 5, and π ≈ 3.14, compute 2 × 3.14 × 5 = 6.28 × 5 = 31.4. So the circumference is about 31.4 units. The value 31.42 would come from a more precise π or a different rounding, but using the given approximation gives 31.4. The other numbers don’t align with 2 × 3.14 × 5.
