# Cylinder volume

There are two definitions of a cylinder in geometry: 1) A cylinder is a simple geometric body obtained by rotating a rectangle around one of its sides. 2) a cylinder is a geometric body bounded by a cylindrical surface and two parallel planes that intersect it. The formula for finding the volume: **V = π ⋅ r 2 ⋅ h**

**Cylinder volume through radius and heightу**

**Rotation radius r**

**Cylinder height h**

**Cylinder volume through the base area**

**Base area S**

**Cylinder height h**
