it is the circle that ut the hemisphere into two part.
the set f all points of the plane which lie either on the circle or inside the circle form the circular region
A body of water you can use for a route, ex. strait, sound river
the definition of perimeter is the distance around a 2-demensional shape,along the boundary of the shape.the perimeter of a circle is called its circumference
Aa closed conic section shaped like a flattened circle
the main definition of diameter is the measurement of straight down the middle of a circle or some other shapes but mainly circles
it is the circle that ut the hemisphere into two part.
A straight route is the path taken in a straight line while the shortest distance between two points on a circle is known as the great circle route. However, while travelling the great circle around the globe, the path ahead will look like the straight route.
The great circle route is the shortest route.It is just that if you plot a great circle path on a flat map (unless it is the equator or a line of longitude) it will look bent - this is an artifact of map projection.The actual difference in route lengths depends on the routes you are comparing.---------------------------------------------------------------------------------------The great circle route is the shortest route between two locations on a "roughly" spherical object like the earth. It is in effect the straight line between two locations along the surface of a sphere.By the straight route - I assume you mean a straight line on a 2D map. This usually does not coincide with the great circle route. The difference in length between a so-called straight route and a great circle route would then vary based on both the map projection selected and the location of the two endpoints of the journey.-----------------------------------------------------------------------------The SHORTEST line between two points on a sphere IS a GREAT CIRCLE.Also, by definition, the shortest line between two points IS the straight route.
Because on a globe, a great-circle route is the shortest route between two places.
Great Circle routes are used because they are the shortest route between two points on the globe.
the shortest air route is a great circle
Great Circle Route
It is the path along a circle that cuts the earth into two equal hemispheres.
-- The 'great circle' route is the shortest distance between any two places on Earth (or on any other sphere). -- A great circle is a circle on the surface whose center is at the center of the Earth. -- The phrase "around the globe" is really not too clear.
I don't know, HA
the greatest advantage of the great circle sailing is that it can be gained by sailing along greatest circle route in high latitude in east and west direction
