Frequently asked questions
What is the formula for Volume of a sphere?
V = 4/3π r³.
What do the letters stand for, and what units are used?
Volume in cm³, Radius in cm.
How do you calculate volume?
Put the values into V = 4/3π r³. For example, with Radius = 5 cm, volume = 523.6 cm³.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (volume, radius) and fill in the others: it rearranges the formula for you.
