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.

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 … WebThe circumference of the Earth can be found by two methods.

WebFeb 6, 2024 · Magali Billen. University of California, Davis. Orbital mechanics is a branch of planetary physics that uses observations and theories to examine the Earth's elliptical orbit, its tilt, and how it spins. Observations of the orbital behavior of planets, moons or satellites (orbiters) can provide information about the planet being orbited through ... WebSo to complete one orbit, it takes circumference/speed = $52\,000 / 2.1\cdot 10^{-4} = 245 \cdot 10^6 {\rm years}$, that is 245 million years. Pretty close to the actual value! Share.
