2 इकाई आंतरिक त्रिज्या और 3 इकाई बाह्य त्रिज्या वाली एक गेंद बनायी जाती है।
अवधारणा:
गोले का आयतन = 4/3π(R3 - r3)
गणना:
गोलाकार गेंद का आयतन = गेंद बनाने के लिए आवश्यक सामग्री।
गेंद बनाने के लिए आवश्यक सामग्री
= 4/3π(R3 - r3)
⇒ 4/3π(33 - 23)
गेंद बनाने के लिए आवश्यक सामग्री = 4/3π(19)
⇒ 76/3π.
गेंद बनाने के लिए आवश्यक सामग्री 76/3π है।
