In geometry, a spherical segment is the solid defined by cutting a sphere or a ball with a pair of parallel planes. It can be thought of as a spherical cap with the top truncated, and so it corresponds to a spherical frustum. The surface of the spherical segment (excluding the bases) is called spherical zone. Geometric parameters for spherical ...
Since June 6, 2017, the Prime Minister and the Ministry of Public Security have deployed officials to Tay Ninh to decide to include the Dau Tieng water reservoir project in the list of important projects related to national security. [19] [20] By June 2019, the first solar power plant was established on the submerged area within the Dau Tieng ...

Provided neither plane is tangent to the sphere, this forms a spherical segment of two bases. Also called a spherical frustum. If one plane is tangent, then a spherical cap is formed. If both are tangent, then we recover the sphere.
In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane. It is also a spherical segment of one base, i.e., bounded by a single plane. If the plane passes through the center of the sphere (forming a great circle ), so that the height of the cap is equal to the radius of the sphere, the spherical ...
Contrary to the first postulate ("that between any two points, there is a unique line segment joining them"), there is not a unique shortest route between any two points (antipodal points such as the north and south poles on a spherical globe are counterexamples); contrary to the third postulate, a sphere does not contain circles of arbitrarily ...
Dầu Tiếng is a rural district of Bình Dương province in the Southeast region of Vietnam. As of 2003, the district had a population of 92,592. [1] The district covers an area of 720 km 2. The district capital lies at Dầu Tiếng township. [1] The district had a base with the same name during the war in Vietnam.
In geometry, a spherical sector, [1] also known as a spherical cone, [2] is a portion of a sphere or of a ball defined by a conical boundary with apex at the center of the sphere. It can be described as the union of a spherical cap and the cone formed by the center of the sphere and the base of the cap.
