Hi, so we want the volume of the cylinder.
00:02
So volume of cylinder is pi times the radius square times the height under answer to nearest hundredth and cubic meter.
00:12
All right, so here's a problem.
00:13
You didn't tell me what these numbers are as one of these the radius is one of these the height i don't know you didn't tell me that so i'm gonna show different answers depending on what are to hr.

Okay, so if this three is the radius and this 11's the height your answer is about 311.
00:32
If this 3 is a diameter, so that happens a lot with these volume problems that give you a diameter, well, you got to divide this by 2 and use that as a radius, so that would be 1 .5, and you'd end up with like about 78 as an answer.

If sometimes i've seen it where like, hey, that's the height and that's the radius, well, if 11 is the radius and 3 is the height, then your answer is like 1 ,140...
