In this how-to video, the author, , Davitily, has a simple drawn out diagram of a cone figure and it's measurements, and also has the mathematical formula of how to find the surface area of this and any other cone figure.
The video does not have sound, but it does have an animated blue box that outlines each step as annotations appear on the screen to add further detail to each step being outlined by the box.
Also using colored and animated arrows to point out details from the diagram that remains on the screen, the author does a great job of showing a detailed step-by-step method to find the surface area of a cone.
