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

\[ \text{Surface Area} = 2\pi r^2 + 2\pi rh \]

where:

  • \( r \) is the radius,
  • \( h \) is the height.

Given:

  • The width of the cylinder is 2 yards, so the radius \( r \) is half of the width: \[ r = \frac{2}{2} = 1 \text{ yard} \]
  • The height \( h \) is 3 yards.

Now, plug the values into the formula using \( \pi \approx 3.14 \):

  1. Calculate the area of the two circular bases: \[ 2\pi r^2 = 2 \times 3.14 \times (1)^2 = 2 \times 3.14 \times 1 = 6.28 \text{ square yards} \]

  2. Calculate the lateral surface area: \[ 2\pi rh = 2 \times 3.14 \times (1) \times (3) = 2 \times 3.14 \times 3 = 18.84 \text{ square yards} \]

  3. Add both areas to find the total surface area: \[ \text{Surface Area} = 6.28 + 18.84 = 25.12 \text{ square yards} \]

Therefore, the surface area of the cylinder is 25.12 square yards.
