Cone Geometry and Calculations

The video tutorial explains how to find the volume of a right cone with a circular base. It uses a radius of 5 cm and a height of 15 cm, approximating Pi as 3.14. The process involves calculating the area of the base, multiplying by the height, and then applying the formula for the volume of a cone. The final calculation is performed using a calculator, resulting in a volume of 392.2 cm³.
