For a circle with a diameter of 14 cm, what is its circumference? (Use π≈3.14)

For a circle with a diameter of 14 cm, what is its circumference? (Use π≈3.14)

• A. 43.96
• B. 44.0
• C. 43.96
• D. 45.24

Answer: (C)

To find the circumference of a circle, you can use the formula: Circumference = π × diameter. In this scenario, the diameter of the circle is given as 14 cm. Substituting the diameter into the formula along with the approximate value of π (3.14), we compute the circumference as follows: Circumference = 3.14 × 14. Now, carrying out the multiplication: 3.14 × 14 = 43.96 cm. Therefore, the calculated circumference of the circle is 43.96 cm, which matches the given choice. This confirms the selection, as this option accurately reflects the correct mathematical application of the formula for the circumference of a circle using the provided diameter.
