Your measurements are not those of a sphere. The 12 inches and 6 inches are OK, but if it's a sphere, its height would equal the diameter and be equal to 12 inches.
Please repost your question and change either the height or the word, "Sphere".
A sphere of radius 12 inches cannot have a height of 23 inches. It is, in that case, a flattened sphere and a lot more detailed information about the flattening is required to find its volume.
The radius is 32 because the height of the hemisphere (which is half of a sphere) is the same thing as the radius (which is half the length of the diameter); the radius is the distance from the center to any point on the edge or surface of the circle/sphere.
A sphere's height will always be the same as its diameter.
The radius of a sphere is 1/2 of its height.
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2

You need to follow these steps:1) Divide the diameter by 2, to get the radius. 2) Use this radius in the standard formula for the volume of a sphere. 3) Divide this result by 2, to get half a sphere.

A sphere with a radius of 30 inches has a diameter of 60 inches, a surface area of 4π(30 inches)^2 ≈ 11,310.7 square inches, and a volume of 4/3π(30 inches)^3 ≈ 113,097.3 cubic inches.

A sphere with a radius of 7 inches has a volume of 1,436.76 cubic inches.
The surface of a sphere is calculated pi*d2 or 4 *pi*r2 So if you have a sphere with diameter 8 (units) the area is 804.25 inches squared
A sphere with a radius of 3 inches has a volume of 113.1 cubic inches.
The height of a sphere is the same as its diameter, and the formula for volume of a sphere is (4/3) x pi X radius cubed. The radius is half the diameter, and in this instance the formula yields about 113.0973355 cubic inches if the value 6 is considered exact, otherwise 1.1 X 102 cubic centimeters to the justified number of significant digits.The formula for calculating the volume of a sphere is: Volume 4/3 * π * r3. Note that the given height of the sphere 6cm is equal to the diameter of the sphere. The formula requires a radius or half the diameter. Therefore, the Volume 4/3 * 3.14 * (3 * 3 * 3 or 27) = 113.0399 or 113.04 cubic centimeters.Note that the given unit of measurement is in centimeters. You cannot just change the unit of measurement to inches and back to centimeters. The above calculation is also a few hundredths off.
The radius is half the diameter of a ball (or sphere), so if diameter is 7.91 units the radius is 3.955 units.
