Answer:

The fourth one

Explanation:

Surface area of a cylinder:
SA=2\pi rh+2\pi r^2

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


SA=2\pi (3)(14)+2\pi (3)^2

This equation matches with answer choice D
