How do you find the volume of a hemisphere

The video tutorial explains how to calculate the volume of a hemisphere using the formula for the volume of a sphere. It begins by introducing the formula for a sphere's volume and then adapts it for a hemisphere by dividing by two. The teacher provides a practical example using a given radius, demonstrating the calculation step-by-step. The importance of using correct units, specifically cubic units, is emphasized throughout the tutorial.
