22*22*22=10648
v=(4 pi r^3)/3
r=1
v=4pi/3
10648/(4pi/3)=2542.02
This number doesn't seem right to me but I checked with two others and they didn't see any flaws, so, it should be right.

∙ 12y agoBalls can be spherical or not. The (American) football uses a ball that is far from spherical. However, a sphere is a perfect geometrical solid with a uniform radius, and a ball made in that shape is quite suitable for games. It will, for instance, bounce in a predictable way.
If you tap on them, one of them may "sound hollow". In general, certain waves (like sound) will be affected differently, depending on whether the balls are hollow or solid.If you tap on them, one of them may "sound hollow".

the moment of inertia of a solid cylinder about an axis passing through its COM and parallel to its length is mr2/2 where r is the radius.
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)

The inner core of the Earth is a solid metallic sphere made primarily of iron and nickel with a radius of about 1216 kilometers. It is surrounded by the liquid outer core and the solid mantle.

solid angle is the ratio of the intercepted area dA of the spherical surface , described about the apex O as the centre ,to square of its radius r
Yes, Jupiter is approximately spherical in shape due to its own gravity pulling on the material within the planet. This gives it a rounded appearance.
An example is sulfur.
Yes,for example Mg (Magnesium) is a metallic solid.
no not all metallic are solid at room temperature.
It is: (4//3*pi*83) divided by (4/3*pi*13) = 512
Sulfur is an element that is a yellow non-metallic solid.
Metallic, solid metal
