To calculate the surface area of a cone, you can use the formula:
\[ \text{Surface Area} = \pi r (r + l) \]
where:
- \( r \) is the radius of the base of the cone,
- \( l \) is the slant height of the cone.
Since you've provided options without numerical values for the radius or slant height, I'm unable to compute a specific answer. However, you can substitute the values of \( r \) and \( l \) into the formula using \( \pi = 3.14 \) to find the surface area.
If you provide the measurements, I can calculate it for you. Otherwise, you can check which option best matches your calculated value once you substitute the known dimensions.
