and it's going to find the volume of a cylinder
- 00:23
wu We also have a formula for creating power puff
- 00:26
girls but that's another lesson So back to the cylinder
- 00:29
right to find the volume of a cylinder we use
- 00:31
the formula v equals pi r squared h and we
- 00:34
need the value of the radius and the height to
- 00:36
fill it in Luckily the question tells us values of
- 00:39
the radius nights while we have to do is plug
- 00:41
in chug radius is seven centimeters in the highest fourteen
- 00:44
plug Those in we've got v equals pi seven squared
- 00:48
fortin on we just have to solve So seven squared
- 00:52
forty nine forty nine times fourteen in texas is six
- 00:55
eighty six and then we got that times pi is
- 00:58
about three point one four that gets us in about
- 01:00
twenty one fifty five So there we have it One
- 01:03
approximate volume of twenty one fifty five point one three
