V.4 How do they differ?

Volume

What happens to the volume of a cylinder with radius 4 in. and height 3 in. when you scale the height?


Damien's "Double the Height" Method
If I double the height, I have a new height of 6in.
Let me calculate the volume with the new height.
Doubling the height causes the new volume to be two times the original!
V = πr2h
V = π(4)2(6)
V = 96π in.3
96π 48π
