The formula to calculate the surface area of a cone is: πr(r + √(h^2 + r^2)), where r is the radius of the base of the cone and h is the height of the cone. Given that the diameter is 18 meters, the radius (r) would be half of that, which is 9 meters.
Surface area = π * 9 (9 + √(54^2 + 9^2))
Surface area = π * 9 (9 + √(2916 + 81))
Surface area = π * 9 (9 + √(2997))
Surface area = π * 9 (9 + 54.737)
Surface area = π * 9 (63.737)
Surface area = π * 572.633
Surface area ≈ 1,802 m2
Therefore, the closest answer is 1,802 m2
