Circles and PiCone Volume

Volume of a Cone

We previously found the volume of a cylinder by approximating it using a prism. Similarly, we can find the volume of a cone by approximating it using a pyramid.

Here you can see a ${n}-sided pyramid. As the number of sides increases, the pyramid starts to look more and more like a cone. In fact, we could think of a cone as a pyramid with infinitely many sides!
