The radius of a circle is 2 millimeters. What is the circle's circumference? Use \( \pi \approx 3.14 \) and round your answer to the nearest hundredth. Submit millimeters

To find the circumference of a circle, you can use the formula \( C = 2\pi r \), where \( r \) is the radius of the circle. With a radius of 2 millimeters and using \( \pi \approx 3.14 \): \( C = 2 \times 3.14 \times 2 = 12.56 \) millimeters. So, the circle's circumference is approximately 12.56 millimeters when rounded to the nearest hundredth. But did you know that the concept of circles has been around for thousands of years? Ancient civilizations like the Egyptians and Babylonians made significant contributions to our understanding of geometry, and the circle has always been a fascinating shape due to its perfect symmetry and endless geometric wonders! In practical terms, the circumference is crucial in various fields. For instance, engineers and architects use it to calculate materials needed for circular structures, or in manufacturing, to design rolling elements like wheels and bearings. Understanding how to compute circumference allows for better planning and materials management in real-world situations!
