The diameter of a circle is 12 kilometers. What is the circle's circumference? Use \( \pi \approx 3.14 \) and round your answer to the nearest hundredth. kilometers

To find the circumference of a circle, we use the formula: Circumference \( C = \pi \times d \), where \( d \) is the diameter. With a diameter of 12 kilometers, we plug in the value: \( C = 3.14 \times 12 \approx 37.68 \) kilometers. So, the circumference of the circle is approximately 37.68 kilometers. Did you know that this formula has been around for thousands of years? Ancient civilizations like the Babylonians and Egyptians made their own calculations and approximations for π. Their methods laid the groundwork for the numerical precision we enjoy today! Circles are all around us in everyday life, from the wheels on your bike to the pizza you order. Understanding the circumference can help with real-world tasks, like calculating the amount of fencing required for a circular garden or the distance covered in a circular track. It’s a handy concept to keep in mind!
