How much paper is used for a label on a can of frosting. The height of the jar is 5 inches and the radius is 1.5 inches
I did SA=2TTrh+2TTr^2
SA=15TT + 2TT2.25
61.3in squared of paper was used for the label
Did I do these steps correctly? Thanks for your help!
If 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
