So this time we're looking at a small cylindrical jewelry case.
00:05
They've given us a diameter of eight inches and a height of three inches.
00:09
We have to find the volume of the case rounded to the nearest thousandth.
00:14
So to find the volume of a cylinder, we have to do pi r squared h.
00:20
So in this case, we have to do pi times four squared times three.
00:26
Remember that a diameter is half of a diameter.
00:31
Or my diameter needed to be cut in half.
00:33
So once i have that, i can go ahead and, oops, wrong way.
00:38
I can multiply, and i'm going to get 48 pi inches cubed.
00:44
But i didn't want inches cubed.
00:46
If you look at my answers, they're all in cubic feet...
