Volume and Surface Area of Pyramids, Cones, Spheres

Geometry and Measures Volume and Surface Area of Pyramids, Cones, Spheres

🎬 Video Tutorial

Volume of Pyramids and Cones: (1/3) x base area x height, where height is always perpendicular to the base.
Surface Area of Pyramids: Add the base area and the areas of all triangular sides.
Surface Area of Cones: Add the base circle area (π×r²) and the lateral surface area (π×r×s), where s is the slant height.
Volume and Surface Area of Spheres: Remember, volume requires r³ cubed, while surface area needs r².
