1. Find the lateral area of a cone with a radius of 7 ft. and a slant height of 13 ft. Use 3.14 for n and round to the nearest tenth.
439.6 f2
324.5 f2
571.5 f2
285.7 f2
Wrong again by the bot.
SA = π(rs)
= π(7)(13)
= 285.9 ft^2
To find the lateral area of a cone, we need to use the formula:
Lateral Area = π * radius * slant height
Given that the radius is 7 ft. and the slant height is 13 ft., we can substitute these values into the formula:
Lateral Area = 3.14 * 7 * 13
Calculating this, we get:
Lateral Area ≈ 285.7 ft²
So, the correct answer is 285.7 ft² (rounded to the nearest tenth).
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 7 ft. and the slant height is 13 ft., substitute these values into the formula:
Lateral Area = 3.14 * 7 * 13
Multiply to find the answer:
Lateral Area = 285.7 f2
Therefore, the lateral area of the cone is approximately 285.7 square feet.
