The video tutorial explains how to calculate the volume of a sphere using the formula V = 4/3 π r³. It provides examples of calculating volume with a given radius and converting diameter to radius. The tutorial also covers finding the radius from a given volume and calculating the volume of a hemisphere and a silo. The process involves using mathematical operations and rounding results to the nearest tenth or thousand as required.
