Web9 Jan 2024 · the surface, S = 2 π R h + π R 2. Solving the first eq. respect to R, you find: h = V π R 2. Putting this into the equation of the surface, you obtaine: S = 2 V R + π R 2. deriving this expression respect to R and putting the result to zero in order to find the minimum, you have: R = V π 3. http://proframkumar.weebly.com/uploads/2/3/8/4/23842103/thin_and_thick_cylinders_-__solved.pdf
