First, the area of two circles, radius 10 inches
Then get the circumference of such a circle and multiply it by the length of the short side (8 inches) to get the area of the wall of the cylinder.
(2 x area of circle) + the area of the vertical wall.
I'm going to let you do the math.
The most important thing in a problem like this is to break it down into pieces that can be easily solved on an individual basis.

If you make your question a little more explanatory - I think I can help you with the formula. You can also find formula's in the front or back of a collegiate dictionary most of the time. It actually depends on who the author is and the year of the publication. Another suggestion is: go to google and click in "math help geometry". Yahoo offers that too, I imagine. If all else fails, call a library at a college if it's on Sunday. They usually are open, or call a bookstore and ask the employee if they could help you find this answer for you with kindness and urgency and leave your number for them to call you back. When/if they do, make sure you ask where/who/what/how they found the information for future reference and then look it up on the Internet. Good Luck! Terri Jo
