I did SA=2TTrh+2TTr^2

SA=2TT1.5(5)+2TT1.5^2

SA=15TT + 2TT2.25

SA=15TT=4.5TT SA=19.5TT

SA=61.261

SA=61.3in^2

61.3in squared of paper was used for the label

Did I do these steps correctly? Thanks for your help!

**Ms. Sue**, Tuesday, March 19, 2013 at 1:50pmIf only the sides, but not the top and bottom are covered with paper >>

A = 2 * pi * r * h

A = 2 * 3.14 * 1.5 * 5

A = 47.1

If the ends are also covered >>

A = 2 * pi * r^2

A = 2 * 3.14 * 1.5^2

A = 14.13

14.13 + 47.1 = 61.23 square inches
