    Lateral Area = 2 * pi * r * h (Area of Base of Cylinder times its height) LA = 2 * pi * 7 * 45 LA = ? ---------------> I think it is 1979 ish. Check @OpenSessame

    You might want to work a few assorted math problems during that year so that you won't begin college math stone cold.

    You could come to Open Study, post ten problems a day for 100 days and get discussions of the problems. That might be fun, or my idea of fun.

    Thanks, i got one question though...Is it possible to get a 100 score on openstudy lol?

    Yes. One person has that score. I think it was arbitrarily assigned. That is, not computer calculated. Nobody knows how the Smart Score stuff works. I was grandfathered in. A year or so ago there was a different scoring method based solely on medal count. I'll see if I can find the icon of the 100 person.
