Eli is making a model castle out of clay one of the roof peaks is in the shape of a cone with the demeanor of 14 in and a slant height of 20 in what is the surface area of the cone peak round your ants to the nearest hundred use 3.14 for pi
To find the surface area of the cone, we need to calculate the lateral surface area.
The lateral surface area of a cone is given by the formula: LSA = π * r * l, where r is the radius and l is the slant height.
Given that the diameter (d) of the cone is 14 inches, the radius (r) can be calculated by dividing the diameter by 2: r = d/2 = 14/2 = 7 inches.
Now, we can substitute the values into the formula:
LSA = 3.14 * 7 * 20
= 439.2 in² (rounded to the nearest hundred)
Therefore, the surface area of the cone is approximately 439 square inches.
