Correct Answer: 46200


Solution : Given:
The curved Surface area of a cylinder = 2640 cm 2
⇒ $2πrh = 2640$
⇒ $r=\frac{2640}{2π×12}$
⇒ $r=\frac{2640×7}{2×22×12}$
⇒ $r =\frac{18480}{528}$
$\therefore r=35$ cm
So, the volume of cylinder = $πr^2h=\frac{22}{7}×(35)^2×12=46200$ cm 3
Hence, the correct answer is 46200.
