Volume of a Cylinder - VividMath.com

[@VividMath]

Depending on your calculator, your answer may be different. Here we use π=3.141592654 to get 254.47. If you used π=3.14 the answer would be 254.34 which is also correct.

[@clead4014]

You should use 22/7 which is very accurate and simple to do

[@VividMath]

hi, thanks for your feedback. i re-checked for you. only when pi = 3.141592654 is the above answer correct. if the pi you are using is (pi = 3.14) then your answer is correct.

[@casualwatcher3386]

Ms Vaughan’s class where u at!!!!

[@sakitoido]

@Patrick Molden he was right. Your answer is also right but his is more correct. He used the actual button Pi. You used 3.14.

[@lddd1911]

this is a nice video but I am still confused when you said 3.14 so where did you get that number from?

[@undray4131]

its pi. its a ratio of the diameter of the circle to its circumference

[@Stevielifts]

😂😂 pi= 3.14 so when you multi play 81xpi it's 81x3.14

[@roastedhd2852]

π = 3.14

[@tonyfoxxbuilds1920]

I'm sure this is a dumb question. Why is it r² and not x by the diameter? If my 6in diameter pipe is now multiplied by 9 instead of 6? I just to know how many gallons I can fit in a 4inx10ft pvc pipe.

But you probably used the whole Pi so that would explain that..

[@chloezaharof1012]

He got that answer because he used the pi key on a calculator while some of us just used 3.14 so it is still around the same number, he is just more precise.

what is the volume of water in a horizontal cylinder has only 3 inches of water if diameter is 20 inches and the cylinder is 72 inches long? (horizontal not standing cylinder) polobest

[@tgalam2170]

Is it right to use 22 over 7 cuz pi numbers are different..22÷7= 3.1428 but pi = 3.1415

[@VividMath]

Yes, usually it depends what variation of π the tests asks you to use.

[@waqarthoughts86]

thank u

[@Thealexismercado]

All of you guys complaining that the answer is wrong, it is not wrong! The answer is 254.47. He didn't multiply only using 3.14. He instead used the whole pi number. He most likely had a "Pi" button in his calculator, that's why his answer is what it is.

[@jamesmcdougall8327]

Guys its 254.34m 3 btw he just does it differently with pie.

[@maricellitong1133]

Well, I know u guys is confused but this guy used the full pi which is 3.1415926536. But u guys are still correct cuz 3.14 is still a pi which the answer will be 254.34. 3.1415926536 IS the real pi cuz its full. But 3.14 is still a pi, 3.14 pi is just for short
