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
