You know that the volume of a box is Length × Width × Height. In other words, it's the area of the box's "footprint" multiplied by the height. It makes sense that the volume of a cylinder would also be the area of its footprint times height. The "footprint" of a cylinder is a circle, and its area is πr². So, the volume of a cylinder is πr²h.

Find the volume of the cylinder
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be increased.
Volume of a CylinderThe volume of a cylinder is the product of the area of its base and its height. Because a cylinder has a circular base, the volume of a cylinder is: Pi x r squared x hwhere r is the radius of the circular base and his the height.
The volume of this cylinder is: 353 cubic units.
The volume of this cylinder is about 8 cm3 (7.9257 cm3).
