The radius of a sphere with antipodes 8 cm apart is 4 cm. The distance between the antipodes of a sphere is the diameter of the sphere. The radius is half the length of the diameter.

A sphere of radius 4000 miles has a circumference of 25132 miles. The distance between any two points on the surface of that sphere is simply 25132 times the angle between the two points divided by the angle of the full circle (360 degrees). If the two cities were ten degrees apart, the distance would be 698 miles. It does not matter if the two cities are on the same meridian or not - angular separation is the only thing that matters, except that the calculation of the angle in three-space is more complex than that in two-space.
No. No. No. No.
Meters and centimeters are two apart on the place value chart. Move the decimal 2 places. 843 cm=8.43 m
The radius of a circle is a line segment joining any point of the boundary of the circle to its centre. A diameter is a line segment from a point of the boundary of the circle which passes through the centre and ends at the boundary on the opposite side.
A sphere with radius 4/pi = 0.6366 cm will fit the bill - after a fashion. Four points, equidistant on the equator, along with a point at each pole. Of the 15 possible pairs, all will be 1 cm apart along the great circle apart from the 3 pairs of diametrically opposite points, which will be 2 cm apart. There is no way in which 6 points can be marked on any sphere so that each of the 15 pairs is the same distance apart.

All spheres are identical apart from their radii. They all have exactly the same shape and so are alike.
If 1 centimeter represents 4 miles, then 10 miles would be 2.5 centimeters apart on the map (10 miles / 4 miles per centimeter = 2.5 centimeters).
3km is equal to 300000 centimeters. 300000 divided by 180000 is 1.6666667 centimeters.
At the Mid-Atlantic Ridge, plates are moving apart at a rate of around 2.5 centimeters per year. This movement is driven by seafloor spreading, where magma rises from the mantle and solidifies to create new crust, pushing the plates apart.
Apart from any rounding errors introduced, yes.
