Hemisphere Definition
The term “hemisphere” can be broken down into “hemi,” meaning half, and “sphere,” referring to a three-dimensional shape. Consequently, a hemisphere is a 3D geometric form that represents half of a sphere, with one side being flat and the other resembling a rounded bowl. It comes into existence when a sphere is sliced exactly at its center along its diameter, resulting in two identical hemispheres. The flat side of a hemisphere is often referred to as its base or face.
Surface Area of Hemisphere
Surface Area of Hemisphere = 3πr2
Where,
- π is Mathematical Constant ( π = 3.142)
- “r” is Radius of Hemisphere
Volume of Hemisphere
Volume of Hemisphere = (2πr3)/3
Where,
- π is Mathematical Constant ( π = 3.142)
- “r” is Radius of Hemisphere
Sphere: Definition, Formulas, Examples, Shapes, Properties
Sphere is a three-dimensional object that is perfectly round and symmetrical in shape. It is a set of points in 3-D space that are all equidistant from a fixed point(center). The distance from the center to any point on the surface of the sphere is the same, and this distance is called the radius. A sphere is defined in 3 axis whereas a sphere is defined only in 2 axis.
In this article, we have explained everything about the Sphere from the Definition of Sphere, Volume, and Surface Area Formula, to Real-life Examples of Spheres. Let’s get a closer look at Sphere in Detail.
