EXPLANATION
If the height of the can is 4 inches and the diameter is 3--> radius=1.5 inches, the area is given by the following relationhip:
[tex]\text{Area}_{\text{label}}=2\pi rh[/tex]
Replacing terms:
[tex]\text{Area}_{\text{label}}=2\pi\cdot1.5\cdot4=12\pi=37.7in^2[/tex]
The approximate area is 37.7 in^2
