thankk you, you helped me!
but why is the first cylinder squared by 3 for the answer?

YAY !!! THANK YOU SIRRR !!!

Thank you so much!!

@yourbfsgf squared by 2 after an answer equals area squared by a 3 after an answer equals volume and if it is not squared by anything its usually perimeter

SOOO helpful!! Thank you!
-
THANK YOU!!! this really helped me on my maths homework :D
-
Good video but watching you use that mouse to write is painful
Thanks tho
-
how a about teach us how to find the height of a cylinder when the volume is given
-
OMG THANK U SOOO MUCH i feel like i can solve the worlds problems now
Thank u so much!!!!

Don't confuse me mbrand lol.. I have this down in my head. I don't want to mess it up. This week May 6th o 2011 I will be retaking my math GED test. This is the only one that I need to get my Certificate. Wish me luck. I need a 410 only to pass.

You were right but you was ment to do pie/r2/h. Height comes last!

Since multiplication is commutative, the formula can be written either way. It's still the same. :-)

first of all its V=(pie)(r2)(h)i know that it doesn't matter but just sayinqq Oh!! and umm can you make a video doinqq a cyklinder and the Diameter=1in. and Hieght=2in and the answer has to be A.0.25 B.0.75 or C. Pie cubic inches it was on my test i WAS CONFUSED cuz it kept givinqq mhee 1.57

Since the diameter is 1 in, that means the radius would be 0.5in.
Put those into the formula and simplify:
V = 2(pi)0.5^2
V = 2(pi)0.25
V = 0.5(pi)
V = 1.57
I think you're correct with 1.57, or if you're to express it in terms of pi, it would be 0.5(pi).
I hope that helps!
