There are various characteristics and attributes that would describe a sphere. A sphere is a perfectly symmetrically round or circular three dimensional object.
You need only one to completely describe its dimensions, although you can make lots of measurements.
Spherical, ffs............
It has a shape of a ball
That would be a sphere
Sphere is one syllable: sphere.
a sphere or 3D circle
By saying: It is a red sphere.
A sphere has one point of symmetry (at its very center) if one considers rotational symmetry in its three dimensions. If one is only considering reflectional symmetry, it would have an infinite number of lines of symmetry.
One
A sphere has one side. Not tricky! Unless the sphere is hollow, which would have two sides, inside and outside.
