Question : The radius of the base of a cylinder is 14 cm and its curved surface area is 880 cm2. Its volume (in cm3) is: (Take $\pi=\frac{22}{7}$)
Option 1: 3080
Option 2: 1078
Option 3: 6160
Option 4: 9240
Correct Answer: 6160
Solution :
Radius, $r$ = 14 cm
The curved surface area of the cylinder = 880 cm
2
.
$2\pi r h$ = 880
$⇒\pi r h$ = 440 ---------(i)
$\therefore$ Volume of the cylinder = $\pi r^2 h=\pi r h × r= 440 × 14= 6160$ cm
3
Hence, the correct answer is 6160 cm
