To find the lateral area of a cone, you need to know the radius and the slant height. The lateral area is the curved surface area of the cone, excluding the base.
The formula to find the lateral area of a cone is: Lateral Area = π * radius * slant height
Given that the radius of the cone is 7 ft and the slant height is 13 ft, we can substitute these values into the formula and calculate the lateral area.
Lateral Area = 3.14 * 7 ft * 13 ft
Lateral Area = 3.14 * 91 ft^2
Lateral Area = 285.74 ft^2 (rounded to the nearest tenth)
Therefore, the lateral area of the cone is approximately 285.7 square feet when rounded to the nearest tenth.
