Volume of a Frustum of a Cone | Two Methods (Formula & Difference of Cones)

In this video, we solve a classic high school geometry problem: finding the volume of a frustum of a cone with bottom radius 10, top radius 5, and height 12. What makes this video special is that we solve it using two different methods: 🔹 Method 1: Using the difference of volumes of two similar cones We construct the original large cone and subtract the smaller removed cone. 🔹 Method 2: Using the standard frustum volume formula We directly apply the formula. Both methods lead to the same result, helping you understand why the formula works, not just memorize it. This video is perfect for students preparing for: ✔ High school geometry ✔ SAT / exam preparation ✔ Competitive math problem solving By the end, you’ll understand the geometry behind the formula and how to approach frustum problems from multiple perspectives.
