Volume of a Cone Calculator

🧊 Volume & surface area (3D). Use the Volume of a cone formula to find volume, radius, height: pick the value you want, type the others, and the answer updates as you go.

V=13πr2hV = \tfrac{1}{3}\pi r^2 h
Volume261.8 cm³

Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.

Worked example

Find the volume when Radius = 5 cm, Height = 10 cm.

Using V = 1/3π r² h: Volume = 261.8 cm³.

Frequently asked questions

What is the formula for Volume of a cone?

V = 1/3π r² h.

What do the letters stand for, and what units are used?

Volume in cm³, Radius in cm, Height in cm.

How do you calculate volume?

Put the values into V = 1/3π r² h. For example, with Radius = 5 cm, Height = 10 cm, volume = 261.8 cm³.

Can I solve for a different value?

Yes. In the calculator above, pick the circle next to any value (volume, radius, height) and fill in the others: it rearranges the formula for you.
