The video tutorial introduces cones, explaining their parts such as radius, height, and slant height. It covers the formulas for calculating the volume and surface area of cones, emphasizing the importance of correctly identifying and labeling these parts. The tutorial includes a practical example where a word problem is solved, demonstrating how to apply these formulas to find the surface area of a cone. The session concludes with a brief mention of the next topic, pyramids.
