The body of a canister's height is four times the height of the lid. If h represents the height of the can's body, which expression could be used to determine the surface area of this canister?
Seeing as the question asks "which expression", I'm assuming it is multiple choice. Care to post those of do you want to challenge the good folks of OpenStudy by not giving out those choices? =p
two pi r squared plus two pi r times the quantity of h divided by four four pi r squared plus four pi r h two pi r squared plus two pi r h plus two pi r times four h two pi r squared plus two pi r h times the quantity of one plus one-fourth
two pi r squared plus two pi r h plus two pi r times four h
you were wrong
Oh oops I see where I went wrong. I shall retreat to my cave in shame.
