Описание: Class 10 Maths Chapter 12 | Surface Areas & Volumes | Ex 12.2 Q7 | Cone + Hemisphere Inside Cylinder | Water Displacement | NCERT

💧 Cylinder me paani bhara hai, uske andar ek Cone aur ek Hemisphere daal do… to paani ka level kitna upar aayega?
Aaj hum exactly isi mind-blowing combination of solids wale question ko step-by-step solve karenge! 🔥

Welcome to Shiksha Board with Deepak Sahu 🙌
In this video, we solve Class 10 Maths Chapter 12 – Surface Areas and Volumes | Exercise 12.2 | Question 7, where:
• Ek cylinder completely paani se bhara hua hai💦
• Usme ek cone aur ek hemisphere rakha jata hai
• Hum find karenge kitna paani displacement (overflow) hoga using volume formulas

⸻

✅ Concepts Covered:

✔ Volume of Cylinder
✔ Volume of Cone
✔ Volume of Hemisphere
✔ Water Displacement Concept
✔ Combination of 3 solid figures

⸻

📘 Formulas Used:
• Cylinder: V = πr^2h
• Cone: V = \frac{1}{3}πr^2h
• Hemisphere: V = \frac{2}{3}πr^3
• Water Displaced = Volume of Cone + Volume of Hemisphere

⸻

🎯 Why this question is important?

✅ Board exams me highly expected question
✅ Real-life water displacement based problem
✅ 3D geometry + formula application
✅ Easy and full marks scoring question

⸻

💡 Best for CBSE, UK Board, NCERT Class 10 students preparing for Board Exam 2025
⚠️ Note: Exercise 12.2 me total 8 questions hain — aur yeh Question 7 hai
