Geometry.a.a solid geometric figure generated by the revolution of a semicircle about its diameter; a round body whose surface is at all points equidistant from the center. Equation: x 2 + y2 + z2 = r2.b.the surface of such a figure; a spherical surface.or a "3D form" of a circle
By applying the process of triple integration (calculus) to the definition of a sphere.
By definition a sphere is 3D. If it were only 2D it would be a circle.
The precise definition of the word 'centres' is the middle point of a circle or a sphere. This means the point is an equal distance from every point on the circle/sphere.
It is the set of all points [from some fixed point] at a distance of 1 unit, where the points on the surface of the sphere are included in the set.
There is no 2D shape that makes a sphere, since a sphere is 3D by definition. The closest thing to a 2D sphere is a circle.
yes..
A sphere.
One half of a sphere.
By definition a sphere is 3D. If it were only 2D it would be a circle.
By applying the process of triple integration (calculus) to the definition of a sphere.
The definition of concave is a curved like a segment of the interior of a circle or hollow sphere.
The precise definition of the word 'centres' is the middle point of a circle or a sphere. This means the point is an equal distance from every point on the circle/sphere.
Hemisphere is one half of a sphere. On a map, the sphere in question is the earth, and a hemisphere is half of it.
a region of the celestial sphere
One half of a sphere, especially of the terrestrial globe.
Yes, for a suitable definition of "round". It is not a perfect sphere.
