Correct Answer: 528 cm 2


Solution : Given, the radius of the cylinder, $r$ = 6, height, $h$ = 8
The total surface of the cylinder
$= 2\pi r(r+h)$
$=2\times \frac{22}{7}\times 6(6+8)$
$=2\times \frac{22}{7}\times 6\times 14$
$=2\times 22\times6\times 2$
$=528$ cm 2
Hence, the correct answer is 528 cm 2 .
