GCSE Maths - How to Find the Volume of a Frustum #114

The video tutorial explains how to find the volume of a thrustum by considering it as a large cone with a smaller cone removed from the top. It details the process of calculating the volume by first finding the volume of the larger cone and then subtracting the volume of the smaller cone. The tutorial provides a step-by-step guide on determining the dimensions of both cones, including using a scale factor to find the smaller cone's radius. Finally, it demonstrates the calculation of the thrustum's volume using the formula for the volume of a cone.

What is the scale factor used to find the radius of the small cone?

Calculate the final volume of the thrustum using the provided dimensions.
