The diameter would be 7.816 feet.
It is the diameter of a body (eg a sphere) in 3-dimensional space rather than in 2-dimensional space (eg a circle).
Volume of a sphere = 4/3*pi*radius3 Volume (space occupied) = 4/3*pi*103 = 4188.790205 or 4189 cubic cm to 4 sig fig
earth
volume of a sphere (the ball) = 4/3*pi*radius3 volume of box - volume of sphere = space remaining 27 - 4/3*pi*1.53 = 12.86283306 space remaining is about 13 cubic inches
A sphere
A sphere contains the most volume to surface area ratio there is and most things sought that shape when molten.
Volume
A circle, rotated about any diameter, will generate a sphere with the same radius. A circle is the locus of all points in 2-dimensional space that are equidistant from a fixed point. A sphere is the locus of all points in 3-dimensional space that are equidistant from a fixed point.
Space was innitialy sphere.
Its the volume
There is no 2D shape that makes a sphere, since a sphere is 3D by definition. The closest thing to a 2D sphere is a circle.
A 100 (US liquid) gallon cube is 23100 cubic inches. The maximum proportion of a cube which can be filled by spheres, using cubic closed packing or hexagonal close packing is approx 74.05%. Consequently, the spheres can occupy at most 17105 cubic inches. This volume implies a maximum of 335 spheres.You cannot divided the volume of the cube by the volume of each sphere because spheres can never occupy all the space in any shape.
