WebFeb 21, 2016 · The average distance of the Earth from the Sun is spproximately #150# million km or #1.5 xx 10^11m#. The orbit of the Earth around the sun is roughly circular (more eliptical really, but let's keep it simple), with a period of roughly #365# days.. So the path that the Earth traverses in #365# days is approximately the circumference of a … WebMar 7, 2024 · The circumference of a circle is equal to the radius, times 2, times the mathematical value for pi (π). So . The radius of the Earth’s orbit is around 149.60 million km (92.96 million mi), although for general reference (and easier to remember) is simply 150 million km. Thus the Earth travels about 940 million km in 1 year.
Earth's orbit is an ellipse with the Earth-Sun barycenter as one focus and a current eccentricity of 0.0167. Since this value is close to zero, the center of the orbit is relatively close to the center of the Sun (relative to the size of the orbit).

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.
