B)

Step-by-step explanation:

Given:

Height of cylinder (h) = 10 yd

Diameter of cylinder (d) = 14 yd

We need to find the surface area of the cylinder.

Solution:

First we will find the radius of the cylinder.

Radius is half of the diameter.

radius (r) =

Now we know that;

Surface area of cylinder is equal to 2 times π times radius(r) times sum of radius (r) and height (h).

Framing in equation form we get;

Surface area of cylinder =

Substituting the given values we get;

Surface area of cylinder =

Rounding to nearest tenth we get;

Surface area of cylinder =

Hence the surface Area of cylinder is .

i think it is 18
