What is the surface area, in square meters, of a cone with a slant height of 8 meters and a radius of 5 meters? Use 3.14 for pi and round to the nearest tenth, if necessary.(1 point) square meters
Surface area of a cone = πr(r + l), where r is the radius and l is the slant height.
Substitute r = 5 and l = 8 into the formula:
Surface area = 3.14(5)(5 + 8)
Surface area = 3.14(5)(13)
Surface area = 3.14(65)
Surface area ≈ 204.1 square meters
Therefore, the surface area of the cone is approximately 204.1 square meters.
