एक चेंडू 2 एककांच्या आतील त्रिज्येसह आणि 3 एककांच्या बाहेरील त्रिज्येसह बनवायचा आहे.
संकल्पना:
गोलकाची मात्रा = 4/3π(R3 - r3)
गणना:
गोलाकार चेंडूची मात्रा = चेंडू तयार करण्यासाठी साहित्य आवश्यक आहे.
चेंडू तयार करण्यासाठी लागणारी सामग्री = 4/3π(R3- r3)
⇒ 4/3π(33 - 23)
⇒ 4/3π(19)
⇒ 76/3π.
∴ चेंडू तयार करण्यासाठी लागणारे साहित्य 76/3π आहे.
