You can calculate the volume of a sphere by using either our sphere volume calculator below or the manual formula provided.
Method #1 – Sphere Volume Calculator
Method #2 – Volume of a Sphere Formula
The volume of a sphere can be calculated by using the formula: v = 4/3 * π * r3
In this formula, the astricks represent muliplication signs, v represents the volume of the sphere, 4/3 represents the fraction four thirds, π represent pi (approximately 3.14), and r3 represents the radius of the sphere cubed.
Next, you’ll need to cube the radius you found in the previous step. To cube a value, multiply the value by itself three times. In this case, it would be (radius * radius * radius).
Now that you have the value of the last item in the equation (radius cubed), you only need to multiply it by the other two items in order to get the volume of the sphere. The other two values are four thirds (approximately 1.3333 repeating) and pi (aproximately 3.14159 continuing). You can divide 4 by 3 and also get the value of pi by using a calculator in order to get a more exact value for the volume of your sphere.
Now you should have the volume of your sphere!
