Homework Help: surface area

Posted by lilman on Monday, April 30, 2012 at 9:33pm.

Find the surface area of the cylinder in terms of pi.
I know the formula is SA=LA+2B, but not sure how to plug in the numbers and get answers. Everytime I try I get wrong answer.
The cylinder has I assume radius 8in and height 20in.
possible answers

352piin^2
320piin^2
832piin^2
448piin^2

It's possible I may have the numbers switched around. Can someone please help?
