Chapter 7 (Ex 7B) Book 3 Mensuration | Volume & Surface Area of Cones

📘 Welcome to the next lesson in our Mensuration series for O Level and IGCSE Mathematics. In this video, we study the volume, surface area, and symmetry of cones. The lesson is based on Exercise 7B from Book 3 (8th Edition), where we solve the questions one by one with clear explanations and diagrams to help you understand each step properly. We begin by revising the key formulas related to cones and then apply them carefully to textbook-style questions. The focus is on developing a strong understanding of curved surface area, total surface area, volume, and symmetry so that you can confidently handle similar questions in exams. In this lesson you will learn: How to calculate the volume of a cone How to find the curved surface area and total surface area of cones Understanding the symmetry of cones Step-by-step solutions to Exercise 7B questions How cone-related questions appear in O Level and IGCSE exams By the end of this video, you will be able to solve problems involving cones accurately using the correct formulas and methods. What’s coming next: In the next video, we will move on to spheres and solve questions from Exercise 7C of Book 3 using the same clear and detailed approach.
