চোঙের পার্শতলের ক্ষেত্রফল = 3168 সেমি2
উচ্চতা = 48 সেমি
অনুসৃত সূত্র:
চোঙের আয়তন = πr2h
চোঙের বক্রতলের ক্ষেত্রফল = 2πrh
গণনা:
⇒ 2πrh = 3168
⇒ 2 x 22/7 x r x 48 = 3168
⇒ r = 3168 x 7/(2 x 22 x 48)
⇒ r = 22176/2112
⇒ r = 10.5 সেমি
আয়তন = 22/7 x 10.5 x 10.5 x 48 = 16632 সেমি3
∴ সঠিক উত্তরটি হল 16632 সেমি3 ।
