Volume formulas
The volume of a box is a × b × c, a sphere (4/3)πr³, a cylinder πr²h and a cone (1/3)πr²h. The calculator also gives the surface area.
How it is calculated
Formula
box: V = a × b × c; sphere: V = (4/3)πr³; cylinder: V = πr²h; cone: V = (1/3)πr²h. The calculator also gives the surface area.
Example
Cylinder r = 2, h = 5 → volume ≈ 62.83.
Frequently asked questions
How do I find the volume of a cylinder?+
The volume of a cylinder is V = πr²h, where r is the base radius and h the height.
How do I find the volume of a sphere?+
The volume of a sphere is V = (4/3)πr³, where r is the radius.
