Questions & Step-by-Step Solutions

What is the circumference of a circle with a diameter of 14 cm? (2023)
  • Step 1: Understand that the circumference of a circle is the distance around it.
  • Step 2: Know the formula for circumference, which is C = π * diameter.
  • Step 3: Identify the diameter of the circle, which is given as 14 cm.
  • Step 4: Substitute the diameter into the formula: C = π * 14 cm.
  • Step 5: Use the approximate value of π, which is about 3.14.
  • Step 6: Calculate the circumference: C ≈ 3.14 * 14 cm.
  • Step 7: Perform the multiplication: 3.14 * 14 = 43.96 cm.
  • Step 8: Round the result to the nearest whole number, which is approximately 44 cm.
