How to Find the Volume of a Frustum

This video tutorial explains how to find the volume of a frustum, specifically focusing on cone frustums. It begins with a definition of a frustum and then details the steps to calculate its volume by finding the volumes of the original larger cone and the smaller cone. The tutorial covers how to determine the radius and height ratio of the cones, emphasizing the importance of using the correct formula. Viewers are encouraged to practice with questions provided at the end of the video.
