సిలిండర్ యొక్క పార్శ్వ ఉపరితల వైశాల్యం = 3168 సెం.మీ 2
ఎత్తు = 48 సెం.మీ
వాడిన ఫార్ములా:
సిలిండర్ వాల్యూమ్ = πr 2 గం
వక్ర ఉపరితల వైశాల్యం od సిలిండర్ = 2πrh
లెక్కింపు :
⇒ 2πrh = 3168
⇒ 2 x 22/7 xrx 48 = 3168
⇒ r = 3168 x 7/(2 x 22 x 48)
⇒ r = 22176/2112
⇒ r = 10.5 సెం.మీ
వాల్యూమ్ = 22/7 x 10.5 x 10.5 x 48 = 16632 సెం.మీ 3
∴ సరైన సమాధానం 16632 cm 3 .
