cylindervolume=hpir^2
V=432
432=hpir^2=original
if each is divided by 3 then
h turns to (1/3)h
r turns to (1/3)r
input and find the effect
(1/3)hpi[(1/3)r]^2
(1/3)hpi(1/9)r^2
move 1/9 to front
(1/27)hpir^2
compared to original volume (which was hpir^2)
so therefor we multiply the original volume by 1/27
432*1/27=16
the new volume is 16 cubic meters
