Surface area of the sphere = 4*pi*63502 = 506707479.1 square km
The Earth is an oblate spheroid, meaning it is mostly spherical but slightly flattened at the poles and bulging at the equator. It has a diameter of approximately 12,742 kilometers at the equator.
It has a slightly smaller diameter around the poles than at the equator therefore it is an oblate sphere or spheroid.
The diameter of the earth at the equator is 12,756 kilometers. The earth slightly bulges at the equator slightly elongating the distance.
The diameter of the earth at the equator is 12,756.32 kilometers or 7,926.41 miles.The diameter of the earth through the poles is 12,715.43 kilometres or 7,901.00 miles.Thus the earth is 59 km or 25 miles wider than it is tall, giving it a slight bulge at the equator.This shape is known as an ellipsoid or more properly, geoid (earth-like), or oblate spheroid (squashed sphere).
umm: "The Earth is round"? ------------------------------------------------ The Earth is not round - it is an oblate spheroid. ---------------------------------------------------------------------------- A (slightly) oblate spheroid seems pretty "round" to me.
The Earth is an oblate spheroid.
The Earth is a spheroid; it has no sides.
You probably mean "oblate spheroid," which is the 3D analogue of an ellipse. The earth and other planets, due to the competition between rotational momentum and gravity, is an oblate spheroid. You can model an oblate spheroid by rotating an ellipse around its shorter axis, just as you can model a sphere by the rotation of a circle around any diameter.
The earth is an oblate spheroid: it is somewhat flattened at the poles and bulges at the equator. As a result, its equatorial diameter is 43 kilometres greater than the polar diameter. It is, therefore not possible to give an answer to your question to the degree of accuracy demanded when you have not specified which measure you want. The average diameter is 12742 km.
