@caitesstr do you know how he got that? and @Clutchboy3 , try to make sure when helping others, you kinda lead them along and let them do some of the work. its great to tell them the answer, but if they don't know how you did it, when they go to do it on a quiz or something it will do no good. thanks and welcome to OpenStudy!

@AwkTeenEver23 he replaced "r" with the numbers that were given for the surface area. which i think you then multipy. (πrs + πr2). for volume - you do the same except multipy then divide by 3?
