Unformatted text preview: , for which corresponding side lengths are in equal proportion. h 10 = r 5 h = 2 r Combine the key formula with any constraint equations. We will make the substitution h = 2 r ( ) into V = 1 3 r 2 h . V = 1 3 r 2 2 r ( ) V = 2 3 r 3 We are now expressing V as a function of one variable, r ....
