Diameter of 8 meters and a height of 22 meters.
00:03
Use pi equals 3 .14 and round your answer to the nearest whole number.
00:08
Okay, so i'm going to use pi times the radius squared times the height to get the volume of the cylinder.
00:18
So i'm going to use 3 .14 times the radius.
00:23
If this is 8, which is i believe that's what it says, then the radius is 4.
00:30
So then 4 squared times 22.
00:34
So 3 .14 times 4 squared, which is 16 times 22.
00:39
And then 3 .14 times 16 times 22 is 354.
00:47
I'm sorry, 352.
00:49
Then 3 .14 times 352 is 1 ,152.

Point 28 and rounding to the nearest whole number is 1 ,105 meters cubed...
