Introdução

Cone Calculator — Find the volume and surface area of a cone. Enter Radius, Height to get an instant, accurate result.

Fórmula

Volume = (1/3)πr²h. Slant height = √(r²+h²). Surface area = πr(r + slant height), where r is the base radius and h is the height.

Passo a passo

1. Enter the Radius.
2. Enter the Height.
3. Click Calculate to see your result instantly.

Exemplo do mundo real

Example: With Radius = 3, Height = 4, the Cone Calculator gives Volume: 37.6991, Surface Area: 75.3982.

Perguntas Frequentes

Does surface area include the base?

Yes, the πr² base circle is included along with the curved lateral surface.

Why is the volume a third of a cylinder's?

A cone with the same base and height as a cylinder always has exactly one-third its volume.

What inputs does the Cone Calculator need?

You'll need to provide: Radius, Height. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Cone Calculator?

The Cone Calculator applies the formula exactly as calculated — Volume = (1/3)πr²h. Slant height = √(r²+h²). Surface area = πr(r + slant height), where r is the base radius and h is the height. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Cone Calculator free to use?

Yes, the Cone Calculator is completely free, requires no signup, and runs instantly in your browser.

Sobre a Calculadora de Cone

The Cone Calculator uses a real, verifiable formula — Volume = (1/3)πr²h. Slant height = √(r²+h²). Surface area = πr(r + slant height), where r is the base radius and h is the height. — so results are accurate every time, not an approximation.
