By definition all spheres are identical in shape because a sphere is perfectly round. That's what "sphere" means. In the same way, all perfect squares are identical and all equilateral triangles are identical. Spheres might be larger or smaller, but the shape of all is the same because there is only one kind of sphere.
True...
yes.
Cones, pyramids, and spheres have.
A diameter is a cord in a circle containing the center of the circle. But some circles are sections of spheres. Not all diameters are diameters of spheres.
-- All regular (equilateral) triangles are similar. -- All squares are similar. -- All pentagons are similar. -- All hexagons are similar. . . . etc. Any regular polygon is similar to all other regular polygons with the same number of sides.
True...
Yes, all spheres are similar to each other because they all have the same shape, differing only in size. Similarity in geometry means that two shapes have the same proportions and angles, and since spheres are perfectly symmetrical and defined by their radius, any two spheres can be considered similar regardless of their size. Thus, any scaling of a sphere maintains its spherical properties.
There is one type - all spheres are similar.
True only if they have different diameters
yes.
They are both 3d demensional shapes.
The hydrosphere.
The ratio of the volumes of two similar spheres is the cube of the ratio of their radii. If the ratio of their radii is 59:1, then the ratio of their volumes is ( 59^3:1^3 ), which is ( 205379:1 ). Thus, the volume ratio of the two spheres is 205379:1.
