8)  Since the labels just cover the sides...

A=2πrh  and the difference between these two labels will then be:

A=2π(1.5*4.5-1*3)

A=2π(6.75-3)

A=7.5π in^2

A≈23.56 in^2  (to nearest hundredth of a square inch)

9)

V=hπr^2  (the picture appears to show diameters and not radii so)

V=(hπd^2)/4

Since the volume is proportional to hd^2 we can just see when that product is equal...

4^2(h)=6^2(6)

16h=216

h=13.5 in
