yes.
True...
Cones, pyramids, and spheres have.
The ratio is 57 cubed. This answer does not depend on the fact that you are comparing two similar pyramids; it works the same for two cubes, two spheres, etc. - in general, for any two similar 3D objects.
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.
The equator divides the earth into the north and south hemispheres.
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.
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.
Yes
It is 8 : 343.
3/4
True...

If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
They are both 3d demensional shapes.
No.
The spheres most affected by forest fires are the flammable spheres.
Two spheres that are symmetric to each other with respect to the origin are called "antipodal spheres." This means that the centers of the spheres are equidistant from the origin but in opposite directions.
