📌 Exercise 9.3 (Question 4) | Similar Solids | Class 9 Math New Syllabus 2025 | Lecture 87

Welcome to Lecture 87 of Math Wala Abu Bakar! In this lecture, we solve Question 4 of Exercise 9.3 from the Class 9 Mathematics New Syllabus 2025. This question is about similar solids, where we find missing volumes, missing radii, missing heights, and missing surface areas by using the concept of ratio of corresponding lengths, areas, and volumes. In this video, we cover all four parts of Question 4 step-by-step: 00:00 Introduction 00:40 (i) Finding the missing volume of a pyramid using side ratios. 04:44 (ii) Using height ratio of cylinders to find missing volume. 11:15 (iii) Using area ratio of cuboids to find volume of similar cuboid. 18:24(iv) Using volume ratio of spheres to find missing radius. You will clearly understand how volume scales with the cube of linear scale factor, and how areas scale with the square of the linear scale factor. This lecture will help you prepare for class tests, board exams, and conceptual understanding. Complete working is explained in simple Urdu + English for all students. 📥 Download Notes / PDF / Solutions from Drive: 👉 #newsyllabus2025 #smartsyllabus2025 #MathWalaAbuBakar #Class9Math #PunjabTextbookMath #MathForBoardExams #StudyWithAbuBakar #LearnMathDaily
