गोलाकार शेलची बाह्य त्रिज्या 13 सेमी आहे आणि शेलची जाडी 3 सेमी आहे.
वापरलेले सूत्र:
गोलाचे घनफळ = 4/3πr3
गणना:
वापरलेल्या धातूचे घनफळ = बाह्य पृष्ठभागाचे घनफळ - आतील पृष्ठभागाचे घनफळ
⇒ 4/3π[133 - 103]
⇒ 4/3π[2197 - 1000]
⇒ 4/3π[1197]
⇒ 4/3 × 22/7 × 1197
⇒ 4/3 × 22 × 171
⇒ 4 × 22 × 57
⇒ 5016 सेमी3
∴ योग्य उत्तर 5016 सेमी3 आहे.
