Volume of Cylinders and Prisms

The video tutorial covers the volume of a cylinder, explaining its properties and how to calculate its volume using the formula V = πr²h. It relates the volume of cylinders to prisms and provides step-by-step examples of finding the volume, height, and radius of cylinders. The lesson concludes with a real-world application involving a swimming pool.
