To find the surface area of a cylinder, we use the formula:

\[ \text{Surface Area} = 2\pi r(h + r) \]

where \( r \) is the radius and \( h \) is the height.

Given:

  • The width (diameter) of the cylinder is 2 yards, thus the radius \( r \) is half of that: \[ r = \frac{2}{2} = 1 \text{ yard} \]

  • The length of the cylinder (height) is 3 yards, so \( h = 3 \text{ yards} \).

Now substituting into the formula:

\[ \text{Surface Area} = 2 \times 3.14 \times 1 \times (3 + 1) \]

Calculating:

\[ = 2 \times 3.14 \times 1 \times 4 \] \[ = 2 \times 3.14 \times 4 \] \[ = 6.28 \times 4 = 25.12 \]

So, the surface area of the cylinder is 25.12.

Therefore, the correct answer is 25.12.
