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 radius of a sphere is 1/2 of its height.
The volume of a sphere with a radius of 13 is: 9,203 units3
The sphere's radius will be 7.973 cm
Radius of sphere is 6 meter.
The radius of a sphere joins the center of the sphere to its circumference.

A sphere with a radius of 7 inches has a volume of 1,436.76 cubic inches.
To work out the area of a sphere, you have to know its radius. Once you know that: -- 'square' the radius (multiply radius times radius) -- multiply that result by 12.5664 The result is near the area of the sphere.
