Hence radius / height $=7/2$

$r=(7/2)h$

We know that the volume of the cylinder $=πr_{2}h$

So,

$8316=22/7×(7/2)h×(7/2)h×h$$h_{3}=216$

$h=6cm$

Therefore $r=(7/2)×6=21cm$

We know that total surface area of cylinder $=2πr(r+h)$

So,

Total surface area $=2×22/7×21(21+6)$Total surface area $=3564cm_{2}$
