With this value for R the meridian length of 1 degree of latitude on the sphere is 111.2 km (69.1 statute miles) (60.0 nautical miles). The length of one minute of latitude is 1.853 km (1.151 statute miles) (1.00 nautical miles), while the length of 1 second of latitude is 30.8 m or 101 feet (see nautical mile ).
More specifically, they can be characterized as orthogonal matrices with determinant 1; that is, a square matrix R is a rotation matrix if and only if R T = R −1 and det R = 1. The set of all orthogonal matrices of size n with determinant +1 is a representation of a group known as the special orthogonal group SO( n ) , one example of which is ...
The following table contains some distances given in astronomical units. It includes some examples with distances that are normally not given in astronomical units, because they are either too short or far too long. Distances normally change over time. Examples are listed by increasing distance.
The Census Bureau created the metropolitan district for the 1910 census as a standardized classification for large urban centers and their surrounding areas. The original threshold for a metropolitan district was 200,000, but was lowered to 100,000 in 1930 and 50,000 in 1940. [12]
According to the United States Census Bureau, the city has a total area of 497 square miles (1,290 km 2), of which 249 square miles (640 km 2) is land and 248 square miles (640 km 2) (49.9%) is water. [38] It is the largest city in Virginia by total area and third-largest city by land area, and by far the largest by water area.
At 26,338 square kilometres (10,169 sq mi), Rwanda is the world's 149th-largest country. [2] It is comparable in size to Haiti or the state of Massachusetts in the United States. [ 3 ] [ 4 ] The entire country is at a high altitude: the lowest point is the Rusizi River at 950 metres (3,117 ft) above sea level.
The dollar sign, also known as the peso sign, is a currency symbol consisting of a capital S crossed with one or two vertical strokes ($ or depending on typeface), used to indicate the unit of various currencies around the world, including most currencies denominated "dollar" or "peso".
