Cylinder Volume Calculator

Free online Cylinder Volume Calculator with instant results.

Calculate a right circular cylinder’s volume from radius and height.

V = πr²h
Enter measurements to calculate.

What the variables mean

V is volume; r is the base radius; h is perpendicular height. The output is expressed in cubic units.

Worked example

For radius 3 cm and height 10 cm, V = π × 3² × 10 = 90π ≈ 282.7433 cm³.

Frequently asked questions

What if I know the diameter?

Divide the diameter by 2 to obtain the radius.

Are units cubed?

Yes. Centimeter inputs return cubic centimeters, for example.
