Volume Calculator for Geometric Solids
Calculate the volume of a cylinder, sphere, cone, prism and other solids. Pick a shape, enter the dimensions and get the result.
How we calculate volume
Choose a solid, enter its dimensions (radius, height, side) and the calculator applies the matching mathematical formula.
Example: volume of a cylinder
Cylinder r=5 cm, h=10 cm: V = pi x r squared x h = 3.14159 x 25 x 10 = 785.4 cm cubed.
Frequently asked questions
How do I calculate the volume of a cylinder?
Use V = pi x r squared x h, where r is the base radius and h is the height.
What is the formula for the volume of a sphere?
V = (4/3) x pi x r cubed, where r is the radius of the sphere.
How do I work out the volume of a cone?
V = (1/3) x pi x r squared x h, one third of a cylinder with the same base and height.
In what units is the volume given?
In cubic units that match the input: cubic centimetres, cubic metres, litres and so on.
How do I convert cubic centimetres to litres?
Divide by 1000: 1 litre equals 1000 cubic centimetres.
Is the calculator free?
Yes, the volume calculator is fully free and works online without registration.
