A sphere is a solid of three dimensions without a base, without an edge, without vertices, and with a face. A sphere is a round body with all points on its surface at an equal distance from the center. The volume of a sphere it should always be measured in cubic units of measurement, since all three spatial dimensions are being taken into account. So if you want to know in detail how to calculate the volume of a sphere, be sure to read this OneHowTo article.
Steps to follow:
1
The formula to calculate the volume of a sphere is: V = (4/3) (π) (r³)
However, it will be much easier to give an example to see how the formula applies, so we will assume that we must calculate the volume of a sphere whose diameter is 28 centimeters.
All you need to do now is connect whatever information the problem gives you, with the formula.
2
To begin with, we have that the diameter of said sphere measures 28 cm. But what does diameter have to do with all this? So it turns out that half the diameter of a circle is called the radius.
In this case, the radio It is 14 cm, that is, half of 28. Keep in mind that if the radius is already given, then it is not necessary to divide the diameter, it is already done. Now, you just have to substitute these values in the formula and perform the operations.

Remember that the order of priority of operations indicates that you must first calculate the powers and then the multiplications. Likewise, in the formula you must also do a multiplication with a fraction, so if you do not remember how to do it, we suggest our article on how to do operations with fractions.
Thus, when calculating the cube of 14, we obtain that the resulting value is 2744 and, in turn, we also substitute the value of the number pi for 3.14 in order to perform the complete multiplication.

And ready! Once all the multiplications have been done, you will obtain that the value of volume of a sphere radius of 14 cm is 11,488.213 cm³; Always remember to be careful with the units of measurement in which you do the calculations, and the cubic unit of measurement of the final result.
