The video tutorial covers further applications of area and volume, focusing on shapes with round parts. It reviews the formulas for the circumference and area of a circle, explaining the relationship between them and the units used. The tutorial also provides a proof for the area of a circle using concentric circles and pizza slice methods, demonstrating how these shapes can be rearranged to form a triangle or rectangle.
