Circumference Circumference of a circle[edit] Circle illustration with circumference (C) in black, diameter (D) in cyan, radius (R) in red, and centre or origin (O) in magenta. Circumference = π × diameter = 2 × π × radius. The circumference of a circle is the distance around it. The term is used when measuring physical objects, as well as when considering abstract geometric forms. When a circle's diameter is 1, its circumference is π. When a circle's radius is 1—called a unit circle—its circumference is 2π.

Circumference of the Planets in Miles Earth. The third planet from the sun is Earth, the only planet known to contain life. Its circumference is just greater than that of Venus at 24,889 miles. Of its total area -- 197,280,733 square miles -- 70 percent is covered by oceans. It orbits the sun at a distance of nearly 93 million miles on a tilted axis of over 23 degrees, creating four distinct seasons.

How large is Earth? How large is Earth? Earth's circumference (the distance all the way around the equator) is 24,901 miles (40,075 kilometers). Its diameter (the distance from one side to the other through Earth's center) is 7,926 miles (about 12,756 kilometers). Earth is slightly smaller when measured between the North and South Poles which gives a diameter of 7,907 miles (12,725 kilometers).

- The circumference of the earth at the equator is almost exactly 24,900 miles. It takes 24 hours for the earth to rotate on it axis so the earth is rotating at a little over 1, … 000 miles an hour (1037.5 miles per hour to be a bit more exact). Answered.

How did Eratosthenes measure the circumference of the earth? The measure of the circumference of the earth made by advanced satellites is approximately 40.008 kilometers. Considering the simplicity and rudimentary but ingenious technique used by Eratosthenes, its calculus approximation was amazing. Only erred in 6.192 kms.

Circumference of the Earth If you like, you can calculate the Earth’s circumference yourself. The formula for calculating the circumference of a sphere is 2 x pi x radius. So, the radius of the Earth is 6371 km. Plug that into the formula, and you get 2 x 3.1415 x 6378.1 = 40,074. It would be more accurate if you use more digits for pi. You might be interested to know that the circumference of the Earth is different depending on how you measure it.

- The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers). But, if you measure the earth through the poles the diameter is a bit shorter - 7,901 miles (12,715.43 km). Thus the earth is a tad wider (25 miles / 41 km) than it is tall, giving it a slight bulge at the equator.

What is the Circumference of the earth? Best Answer: The metric system is somewhat based on the circumference of the earth (at least historically). The distance from the pole (north or south) to the equator is defined as 10,000 kilometers. So, four times 10,000 = 40,000 kilometers.

What Is the Circumference of a Circle With a Diameter of 8 Cm? The circumference of a circle is the distance measured around the edge of the circle. The diameter is the distance measured across the circle through the center. Pi is the ratio found by dividing the circumference by the diameter, resulting in the formula, c/d=pi. This formula is adapted to find each individual variable.

What is Earth's equator? The circumference of the Earth measured at the equator is 24,901.55 miles, or 131,480,184 feet or 40,075.16 kilometers, or 40,075,160 meters.

Microsoft's Windows 10: How the SKUs will skew How those SKUs will stack up is a work in progress. Microsoft has not announced anything yet about its SKU -- officially, stock-keeping unit (unofficially, meaning version) -- plans for Windows 10, other than the fact that there will be more than one when the operating system launches this fall.

- Circumference of the sun: 2,713,406 miles. Circumference of Earth: 24,901 miles. Average hiking speed is 2-3 miles per hour. Since these are going to be huge numbers and it is improbable that anyone would ever be able to set foot on the sun, or walk across an ocean, we are taking some liberties.

Earth radius Earth radius is the distance from the Earth's center to its surface, about 6,371 km (3,959 mi). This length is also used as a unit of distance, especially in astronomy and geology, where it is usually denoted by R⊕. This article deals primarily with spherical and ellipsoidal models of the Earth.

- Compare this with the circumference of the earth (24000000 metres), and the scale is not great enough for the unaided eye to see the earth's curvature.

How was the circumference around the earth measured, and how many miles is it around the equator? Today we know that the circumference of the Earth is 24,901 miles. An easy way to remember is that the tangential velocity of Earth at the equator is about 1,000 miles per hour (this is why countries launch their rockets as close to the equator as possible and they always fly towards the east - the direction of rotation). A day takes 24 hours, so the Earth must be about 24,000 miles around.

- As a consequence, a line of longitude wrapped around the  Earth going through the north and south poles is about 24,859.73  miles, or 40,007.86 km long. That makes the Earth's circumference  about 42 miles longer (about 67 km longer) measured around its  middle than around its poles.

- The length of time it takes for an orbit is equal to 164.79 Earth years. The distance traveled in its orbit can be computed from the orbital speed, and is approximately 28.24 … billion kilometers. The average orbital radius (distance from the Sun) is 4.5 billion kilometers. 2 people found this useful.f the Earth's orbit were a circle, the length of the orbit would be the circumference, C=2 pi r. 2 * pi * (149 600 000 kilometers) = 939 964 522 kilometers Since the orbit is more nearly an ellipses, we could approximate the circumference as C= pi (a+b), but that does not actually improve the accuracy.

Does the Earth Rotate Slower or Faster at the Top? Breaking it down mathematically, the circumference of the Earth at the equator is roughly 40,000 kilometers (24,855 miles), and of course the time that it takes for the Earth to complete one rotation is 24 hours.

Circumference of the Earth If you measure the circumference around the Earth’s equator, you get the 40,075 km figure I mentioned up to. But if you measure it from pole to pole, you get 40,007 km. This is because the Earth isn’t a perfect sphere; it bulges around the equator because it’s rotating on its axis.
