🍩 Ever thought maths could make you hungry? 😋
In this video, Deepak Sahu from Shiksha Board explains a fun and practical NCERT question — Exercise 12.2, Question 3 from Class 10 Maths Chapter 12 – Surface Areas and Volumes.
We calculate how much sugar syrup (30%) is present in 45 gulab jamuns, each shaped like a cylinder with two hemispherical ends.
Learn how to combine the volume of a cylinder and a sphere to solve real-life problems easily!
👉 Concepts covered:
• Volume of cylinder and hemisphere
• Converting total length to height of cylinder
• Application of formula V = πr²h + \frac{4}{3}πr³
• How to find total syrup quantity for multiple objects
🎯 Result:
Each gulab jamun ≈ 25.04 cm³, syrup = 30% → 338 cm³ (≈338 mL) syrup in total!
💡 Perfect for:
• Class 10 NCERT, CBSE, and UK Board students
• Concept clarity and exam revision
• Real-world application of 3D geometry
⚠️ Note: Exercise 12.2 has only 8 questions in total. This is Question 3.
