What is a hemisphere map?
noun. (often initial capital letter) half of the terrestrial globe or celestial sphere, especially one of the halves into which the earth is divided. Compare Eastern Hemisphere, Western Hemisphere, Northern Hemisphere, Southern Hemisphere. a map or projection representing one of these halves.
What is hemisphere and its formula?
As the Hemisphere is the half part of a sphere, therefore, the curved surface area is also half that of the sphere. Curved surface area of hemisphere = 1/2 ( 4 π r2) = 2 π r2.
What is the base of a hemisphere?
From the surface area of a sphere, we can easily calculate the surface area of the hemisphere. The curved surface area of a hemisphere = 2πr2 square units. We know that the base of the hemisphere is circular in shape, use the area of the circle. Where π is a constant whose value is equal to 3.14 approximately.
What is hemisphere formula?
Volume of a Hemisphere Formula
The volume of a hemisphere is half the volume of a sphere, therefore, it is expressed as, Volume of hemisphere = 2πr3/3, where r is the radius of the hemisphere.
What is the hemisphere of India?
India is a vast country. Lying entirely in the Northern hemisphere (Figure 1.1) the main land extends between latitudes 8°4’N and 37°6’N and longitudes 68°7’E and 97°25’E.

What is hemisphere and its properties?
Properties of a Hemisphere
A hemisphere has a curved surface area. Just like a sphere, there are no edges and no vertices in a hemisphere. It is not a polyhedron since polyhedrons are made up of polygons, but a hemisphere has one circular base and one curved surface.
What is CSA and TSA?
Curved Surface Area (CSA) – It includes the area of all the curved surfaces. Lateral Surface Area (LSA) – It includes the area of all the surface excluding the top and bottom areas. Total Surface Area (TSA) – It includes the area of all the surfaces of the object including the bases.
What is sphere and hemisphere?
A circular shaped ball with a diameter or radius is called a sphere. A diameter which is a straight line through the center of a sphere and with the end points on the boundary is called its diameter. The section of the sphere by the plane is called a hemisphere.
