What is the circumference of a circle with a radius of 3 cm using π ≈ 3.14?

To determine the circumference of a circle, the formula used is C = 2πr, where C represents circumference, π is approximately 3.14, and r is the radius of the circle. In this case, the radius is given as 3 cm.

Applying the formula:

1. First, calculate 2 times the radius: 2 × 3 cm = 6 cm.

2. Next, multiply this result by π: 6 cm × 3.14 = 18.84 cm.

Thus, the circumference of the circle with a radius of 3 cm, using π ≈ 3.14, is 18.84 cm.

This calculation aligns with the formula and correctly applies the provided approximation for π, leading to the conclusion that the choice reflecting the circumference is accurate.
