চোঙের বক্রতলের ক্ষেত্রফল = 308 সেমি2
উচ্চতা = 14 সেমি
অনুসৃত সূত্র:
CSA (বক্রতলের ক্ষেত্রফল) = 2πrh
আয়তন = πr2h
যেখানে r হল ব্যাসার্ধ এবং h হল উচ্চতা
গণনা:
CSA = 2πrh
308 = 2 × (22/7) × r × 14
⇒ 308 = 88r
⇒ r = 7/2 = 3.5 সেমি
আয়তন = πr2h
⇒ আয়তন = (22/7) × (3.5)2 × 14
⇒ আয়তন = 539 সেমি3
∴ চোঙের আয়তন 539 সেমি3
