Number 20, it says guess which contains more, the can or the bottle.
00:06
So you should have major guess for part a by now.
00:11
So you have the can of apple juice and the bottle of apple juice.
00:15
And then we are actually going to see which one holds more by calculating their volume.
00:20
So let's call this number one and number two so that when i find volume one and volume two, you'll know which one i'm talking about.
00:27
So our can is just a cylinder.
00:32
So when i find the volume of the first one, i'm just going to use the volume of a cylinder to help me calculate.
00:39
So it's going to be pi r squared h.
00:44
So i know pi is pi.
00:47
Now they give me the diameter, so i'm just going to half my five, which is going to be 2 .5.
00:54
So my radius is 2 .5 since it's half of the diameter.
01:00
And that's squared times my h, which i can see they showed me that, the height of the can is 10 centimeters.
01:13
All right, so i'm going to just calculate out my volume.
01:18
I have 2 .5 squared times 10, putting that into my calculator, and that gives me 62 .5 pi centimeters cubed.
01:30
So that is the volume of the can, so container number one...
