Question

Math help please show work thanks

Answer 1

The curve surface area(CSA) of a cylinder is 2πrh.

Since diameter=1.5 in.

radius=diameter/2

=1.5/2 in.

=0.75 in.

And, the height of the bottle is 5 in.

Now,

CSA=2πrh

=2π*0.75*5 in^2

=15π/2 or 23.56 in^2

The size of the label needed to cover the entire bottle is 15π/2 or 23.56 in^2.
