To calculate the surface area of a cylinder, you can use the formula:
\[ \text{Surface Area} = 2\pi r(h + r) \]
where \( r \) is the radius and \( h \) is the height.
Given:
- Radius \( r = 7 \) yards
- Height \( h = 8 \) yards
- Use \( \pi \approx 3.14 \)
Now substituting the values into the formula:
\[ \text{Surface Area} = 2 \times 3.14 \times 7 \times (8 + 7) \]
Calculating \( (8 + 7) \):
\[ 8 + 7 = 15 \]
Now substituting that back into the formula:
\[ \text{Surface Area} = 2 \times 3.14 \times 7 \times 15 \]
Calculating \( 2 \times 3.14 \):
\[ 2 \times 3.14 = 6.28 \]
Now calculating \( 6.28 \times 7 \):
\[ 6.28 \times 7 = 43.96 \]
Now multiplying by 15:
\[ 43.96 \times 15 = 659.4 \]
Therefore, the surface area of the cylinder is approximately \( 659.4 \) square yards.
None of the given options match \( 659.4 \) square yards, so please double-check the provided options or dimensions.
