To find the lateral area of a cone, you need to know the radius and the slant height. The formula for the lateral area of a cone is given by L = πrℓ, where L represents the lateral area, r represents the radius, and ℓ represents the slant height.
In this case, the radius (r) is given as 7 ft, and the slant height (ℓ) is given as 13 ft. So, you can apply these values to the formula to find the lateral area.
L = π * r * ℓ
L = π * 7 ft * 13 ft
L ≈ 286.13 ft²
Therefore, the lateral area of the cone with a radius of 7 ft and a slant height of 13 ft is approximately 286.13 square feet.
Lateral Area = π * r * s
Lateral Area = 3.14 * 7 * 13
Lateral Area = 181.98 FT^2
