alleryএকটি তাঁবু চোঙাকৃতির (r = 7 m, h = 10 m), যার শীর্ষদেশে 6 m উচ্চতার একটি শঙ্কু রয়েছে। এর আয়তন নির্ণয় করুন (pi = 22/7)।
A1848 m³
B2156 m³
C308 m³
D1540 m³
Answer & Solution
Correct answer: A. 1848 m³
চোঙটি দেয় 1540 m³ এবং শঙ্কুটি দেয় (1/3)(22/7)(49)(6) = 308 m³, তাই মোট আয়তন হলো 1848 m³।
