    Wow, I have a homework full of these types of questions and was struggling with them. My teacher took 1hr to explain to my class on how to solve them and I still didn’t understand the formula of surface area of a cylinder. Your video only took me 5 min to understand which is a lifesaver to me. You really saved me with this and thanks very much with the clear understanding.
