How to find the volume of a cylinder?
This was studied in the primary grades. And now, years later, the question: how to find the volume of the cylinder? The problem poses a dead end.
Cylinder is a geometric body thatIt is bounded by a cylindrical surface, with two parallel planes and a closed guide. If on your fingers, then take a roll of wallpaper, it looks like a cylinder.
The volume of any geometric body is calleda quantitative characteristic of the space occupied by the body or substance. The capacity of the vessel or the volume of the body is determined by its linear dimensions and shape. The definition of volume is associated with the concept of "capacity", which means the volume of the internal space of the vessel, packaging containers, etc.
The volume of any cylinder V is equal to the product of the base area (πr2) to the height h, or
V = πr2h,
where, π is always 3.14
r is the radius of the base.
