alleryएक तंबू एक बेलन (r = 7 m, h = 10 m) के आकार का है जिसके ऊपर 6 m ऊँचाई का एक शंकु बना हुआ है। इसका आयतन ज्ञात कीजिए (π = 22/7)।
A1848 m³
B2156 m³
C308 m³
D1540 m³
Answer & Solution
Correct answer: A. 1848 m³
बेलन का आयतन = 1540 m³ और शंकु का आयतन = (1/3)(22/7)(49)(6) = 308 m³, अतः कुल आयतन = 1848 m³ है।
