Surface Area of a Cylinder - VividMath.com
Get your free lessons: vividmath.com
Use the Surface Area of a Cylinder formula (A=2πrh+2πr^2) to solve for the Surface Area.
See all Surface Area lessons: vividmath.com/geometry/ge-sur...
Steps:
1. Find the radius of the cylinder. Simply divide the diameter by 2 (recall that the radius is equal to half the diameter)
2. Substitute the known values (radius and height) into the Surface Area of a Cylinder Formula (A=2πrh+2πr^2) and solve.

In this video we use _π = 3.141592654_ There are different variations of *π* you may use: Using _π = 3.14_ the answer is: *828.96*
U have no idea how helpful this is, every other video is hard to understand.
i have an exam tomorrow, this helped a lot. Thank you!
wait meters... that's a big flower pot O.O

Please note that we a finding the surface area of an "open" cylinder. It means we do not have a lid.

if there is a lid would the formula be 2 pi r squared + 2 pi r h ?
U explain so well
Very helpful, Thank You!!
So informative I really appreciate it. I thought it was simple and explained very well thank you.
THANK YOU 🙏 you helped me understand this correctly.
thank you very much you help me to my homework. thank you very much again 😀 now I know how to get the volume of pyramid and cylinder..... I will subscribe, like , and share this.... thank you again 😊😊😊😊😊
thanks
thank you it really helped me i will watch this instead of maths at school
Thanks! Great help :)
I like how he shades the bottom side of the box and on the right. I mean starting from here 5:44
Very easy to comprehend thank you. ☺️

this helped me a lot thanks vivid math but i just have one suggestions, just put the decimal point lower because the place that you put it could result in multiplication

If i utilize this formula to get the radius works? 2pi.r=d? 2(3.14)(x)=12 ?

How do you find total surface area
what is the different between area , total surface area and surface area?
is the lid always going to be off or?

@artsnow8872

You multiply the diameter (12m) by 3.14 (pi). Radius squared (r^2) would be used to find area.
thank you I got it 👍👍👆👆☝👊🎉🎈🎆
Wait what, there's no lid?
What about how to find the area with the lid on? Is there a video for that, or...?

If you want a lid on it just use the top formula. Surface Area = 2πrh + 2πr^2.

When your working with just a circle is it just the number x 3.14

no it is called pi. So the formula for the cylinder is Pi (3.14) x r squared

I understand this better than when I was thought this in school.
instead of halving the diameter then double it ,just write it itself
Why exclude the lid?

if he's substituting the formula, shouldn't he say 3.14 instead of pi? And you can see him looking off to the side for the answers.

If you see in the vid, he says that the top does't count since he doesn't want a lid on the cylinder. So instead of 2pirh + 2pirsqrt, it will be just 2pirh + pirsqurt

Let me help you SA=2×pirh×6×19+pirh+6squre = 2×(3.14)×6×19 =716.28+(3.14)+36 716.28+113.10 =829.38// Note pirh=(3.14)

Ok, let me ask you, where did he go wrong in the equation? He stated at the beginning that the cylinder had a open lid, which means we don't count the 2 of the equation, 2 pi R squared, which leaves us with only pi R squared, the rest can be done on calculator. If I am wrong, please point it out, because I'd like to know. Edit: The 2 would stand for the two lids of the cylinder.

Daniel Rinnunga hi! the formula is 2 πrh + πr square...the final answer needs to be 828.96m square. In details : 2 x 3.14 x 6x 19 + 3.14 x6 x6 = 828.96m square
