The largest sphere that can fit around Earth is the geocentric celestial sphere. This imaginary sphere has Earth at its center and encompasses all celestial objects visible in the sky.
A sphere is a whole, and a hemisphere is a part or half.
If by "flattened" you mean "like someone took a sphere and sat on it", that would be an oblate spheroid.
No, a coin is not a sphere. Coins are typically circular in shape, and their structure is flat with two sides. A sphere is a three-dimensional round object in which all points on its surface are the same distance from its center.
The inside of a planetarium is a sphere with the stars and planets projected on to it. The celestial sphere is an infinite sphere that we imagine has the stars and planets on it. On the celestial sphere only an object's direction matters and its distance is ignored. A viewer at the centre of the planetarium sees stars and planets as they appear in the sky, but viewers in all the seats see approximately the right view.
I don't know what you mean but, yes a basketball is a sphere.
The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.
The hydrosphere is all the water biomes as one - there is also the atmosphere and the lithosphere. These mean air sphere and soil sphere respectively. These 3 (Hydro, Soil and Air) all together make the biosphere.
The sphere that we all live on is called the Earth. (It is not a perfect sphere, but close enough)
no. a sphere has no sides at all. no sides,no vertex.
The biosphere is the biggest sphere among all.
Half a sphere is a hemisphere or the shape of a ball cut in half.
The correct answer is Sphere. All of these are geometric shapes, however only the sphere is a 3 dimensional one.
celestial sphere A+
A rounded figure that has all surface points equidistant from the center is a sphere. A common object that is a sphere is a tennis ball.
celestial sphere A+
The surface of a sphere. It cannot be a sphere since points which are not on its surface will be nearer to the centre.
