Answer:

197.92 in^2 or 198 in^2

Step-by-step explanation:

Helena needs to cover the top and bottom so do the formula 2[tex]\pi[/tex][tex]rh[/tex]

we know:

height  = 14 inches

diameter = 4.5 inches

radius = diameter / 2

radius = 4.5/2

radius = 2.25

Now plug the values into the formula.

2[tex]\pi[/tex][tex]rh[/tex]

2[tex]\pi[/tex](2.25) (14)

6.28 (2.25) (14)

14.14 (14)

= 197.92 in^2 ---> 198 in^2
