It is not exactly a sphere, the longest axis is 15km and the shortest one is 8km.
We live on a sphere. Calculating 'shortest' distance on the sphere is not a simple trig problem, you may need spherical trig.
It is not exactly a sphere, the longest axis is 15km and the shortest one is 8km.
Consider the Earth as a sphere - the fact that it is oblate is only of minor significance. The shortest route on the surface of a sphere is an arc of the Great Circle. This is a circle whose centre is at the centre of the sphere and which passes through the start and end points.
A great circle is any circle on the surface of a sphere whose center is at the center of the sphere. The shortest distance between two points on the surface of a sphere is a part of the great circle that passes through them.
It is the shortest distance between two points on a sphere, where the sphere in question is the earth. Particularly long airline flights follow great circle routes.
If talking in terms of the shortest distance around a sphere, the answer is NO.
actually, there is, depending on your definition of polygon, and your definition of a line segment. A line segment is the shortest path btwn two points, right? So take a sphere and pick any two points on that sphere. The shortest path between them on the surface of the sphere would be a "curve" along the surface, but it's the shortest path between the points, so it technally is a line segment. Take two of these line segments that intersect at two points, and there is your two sided polygon!
no it is not a perfect sphere because the average classroom globe shows landforms and mountains on the globe which makes it not as smooth or round
On average 16-18
That's called a "great circle" of the sphere. -- It's any circle whose center is at the center of the sphere. -- Its diameter is equal to the diameter of the sphere. -- Its area is equal to 1/4 the surface area of the sphere. -- The shortest distance between any two points on the sphere is along the piece of the great circle on which they lie. (There's only one, unless the two points are the opposite ends of a diameter.)
A sphere is so strong because it is geodesic. It is strong because all the average strength are very strong.
