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.
The volume of a sphere with a radius of 13 is: 9,203 units3
The volume of a sphere with a radius of 4cm is about 268cm3
The volume of a sphere with a radius of 18 is about 24,429 units3
The volume of a sphere with a radius of 2cm is about 33.5cm3
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.
