WebAnd so see how simple it was for us to get this. But notice that, according to our modern measurements, the average circumference of the Earth, because it's not a perfect sphere, is around 24,900 miles. So we were only about 100 miles off with this seemingly primitive method, which is about half a percent off. WebDec 14, 2024 · Determine the radius of a circle. Let's assume it's equal to 14 cm. Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm. You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm². Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm.
