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

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

where:

  • \( r \) is the radius,
  • \( h \) is the height, and
  • \( \pi \) can be approximated as 3.14.

Given:

  • Height \( h = 8 \) yards
  • Radius \( r = 7 \) yards

Now, plug the values into the formula:

  1. Calculate \( h + r \): \[ h + r = 8 + 7 = 15 \]

  2. Now calculate the surface area: \[ \text{Surface Area} = 2 \times 3.14 \times 7 \times 15 \]

  3. First, calculate \( 2 \times 3.14 = 6.28 \).

  4. Then, multiply \( 6.28 \times 7 = 43.96 \).

  5. Next, multiply \( 43.96 \times 15 \): \[ 43.96 \times 15 = 659.4 \]

Thus, the surface area of the cylinder is \( 659.4 \) square yards.

However, please verify that those options match because the computed value does not seem to coincide with the given responses. If rounding rules or approximations were mistakenly altered in the options presented, that can lead to discrepancies. In any case, based on the calculations, the correct surface area is \( 659.4 \) square yards.
