I love how clearly he speaks explaining every single detail unlike the other videos that I watched this one is the best! I was working on my homework for 5 hours until I saw this video! God bless this man!!!
If you are struggling with finding a good video that helps you understand how to find the surface area of a cylinder then this is the right video for you. I had such a hard time understanding how to do this and I cant believe how fast I learned it just by watching this 10 minute video. The way he explains everything is so detailed and clear. He literally teaches you step by step. I love him !! Thank you so much ((:
Viewed a couple of videos before this video and didn't understand. This video is more explanatory, showed the rules to use. I practice two different cylinder measurements and remember all the steps and can't believe it. Thank you very much for explaining.
I was getting damaged during quarantine that I couldn't even tell the difference between finding the area of a rectangle and circumference of a circle but this video helped me a lot thank you
This is excellent. I found this very useful. What I am not understanding though is the formula that I read (as part of my functional maths) It just confuses me when I read the formula. The steps here are great.
This is helping SOOOOO MUCH, when i hear my teacher talk all i hear is a robotic voice. Ur voice is extremely somehow pleasant to hear, which makes it extremely easy to learn. TKS
I'm wondering how you might calculate the reverse- specifically a 3 dimensional shape eg 150cm x 200cm x 8cm rolled from the 150cm edge as a cylinder, and also the dimensions as a cylinder when rolled from the 200cm edge. This problem I totally melting my brain. Please help!! Thanks
What do you think? If you have one can of soup (a cylinder), and you stack another can of soup the same size on top of it, the height doubles, what happens to the surface area? You can also plug in a couple of valued for the height and see if doubling it makes the overall surface area double. Let me know how your research goes. Good luck! :)
That answer is correct if you use the pi symbol on your calculator. If you round to 3.14 the answer I have is correct. That is why I used the wavy sign that means approximately equal to instead of the equal sign. Good job getting the exact answer!
I think that sounds like it should get you the same result. What you are doing in that formula is finding the circumference of the circle (2xpixr) and multiplying it times the height, that gives you the surface area of the sides, then to get the area of the circle you do (pixrsquared) then multiply that times 2 as there are two ends that are circles.
I'm not sure which question you are looking at, there are a lot of practice problems. I went through them briefly again and can't see one that would give 602.88. Go through and double check then let me know. Thanks!
