Answer: 251 square meters.
Explanation:
You need to use the formula for calculate the lateral surface area of a cone:

Being "r" the radius of the cone and "l" the slant height.
Calculate the radius:

Now that you know the radius and the slant height of the cone, you need to substitute them into the formula for calculate the lateral surface area of the cone:

Therefore, the closest choice to the lateral surface area of the cone is: 251 square meters.
