Answer:
The fourth one
Step-by-step explanation:
Surface area of a cylinder: [tex]SA=2\pi rh+2\pi r^2[/tex]
where r = radius and h = height
We have a given height of 14cm and a given diameter of 6cm
We need the radius, not the diameter
To convert diameter to radius we simply divide by 2
6 / 2 = 3
so R = 3
We now plug in the given values into the formula
[tex]SA=2\pi (3)(14)+2\pi (3)^2[/tex]
This equation matches with answer choice D
