Welcome to the thrilling world of cone volume calculations! Ever wondered how something so pointy could contain so much space? Well, wonder no more! Just like a magician pulling a rabbit out of a hat, we’re about to reveal the secrets of the humble cone.
The magic formula to calculate the volume of a cone is V = 1/3 * π * r² * h where r stands for the radius of the base, h is the code word for height, and V represents the volume.
