Truncated Cone (Posted on 2004-01-23) Difficulty: 3 of 5
If you have a truncated cone such that its upper base has a radius of a and the radius of its [larger] lower base is b, and a height h (between bases), how could you figure out its surface area using geometric reasoning?

top+bottom=pi*(a^2+b^2)
side surface=h*(b/a)*pi*(a+b)
add up =pi*(a^2+b^2+h*(b/a)*(a+b))

just by looking at it
