Jennifer is making strawberry jam, and she is
storing the jam in glass jars that are 3 inches in
diameter and 4 inches in height. If she wants to
make labels to cover the entire lateral surface of
each jar, how big must each label be?

I keep getting the wrong calculations like 28.26 or more, and it doesn't make sense to have a 28.26 inch label on a jar. Please help me.

Sorry I had a lot of things written here but all got deleted because of a bug on this site. 
Anyways just use this formula $$Area = \pi dh$$
d is the diameter and h is the height.

>28.26

I got 28.27 square inches. Your answer is correct.

I used more digits of pi for the calculation and that may be the .01 dscrepancy between our answers.

The unit of measure are area in this case is square inches which is not the same as inches.
