Find the lateral area of a cone with a radius of 7ft. And a slant height of13ft .use 3.14 for pie and round to the nearest tenth
AAAaannndd the bot gets it wrong yet again!
even given the right numbers, it gets the wrong answer!
3.14 × 7 × 13 = 285.74

To find the lateral area of a cone, you need to use the formula:
Lateral Area = π * radius * slant height
Given that the radius is 7ft and the slant height is 13ft, we can substitute these values into the formula:
Lateral Area = 3.14 * 7ft * 13ft
To calculate the answer, multiply 3.14 by 7 to get 21.98, and then multiply that by 13 to get 285.74. Finally, round the answer to the nearest tenth:
Lateral Area ≈ 285.7 square feet
Therefore, the lateral area of the cone is approximately 285.7 square feet.
