A radius of a sphere is the distance from its centre to its surface. It is also half of the diameter.
If you know the circumference of a circle, you can calculate its radius.
Circumference divided by Pi divided by 2 = radius.

Treat the 3D sphere as a 2D circle. The radius for the sphere is the same radius as for the circle. No matter where on the sphere you place a mark, the distance (radius) from the mark to the centre of the sphere will always be the same as the circle.
The sphere's radius will be 7.973 cm
Radius of sphere is 6 meter.
The radius of a sphere is 1/2 of its height.
