To find the surface area of a cone, we need to add the area of the base to the lateral surface area. The formula for the lateral surface area of a cone is given by:
Lateral surface area = π × r × l
where r is the radius and l is the slant height.
Using the given values, the lateral surface area is:
Lateral surface area = 3.14 × 5 × 8 = 125.6 square meters (rounded to the nearest tenth)
The formula for the area of the base of a cone is given by:
Base area = π × r^2
Using the given radius, the base area is:
Base area = 3.14 × 5^2 = 78.5 square meters
Now, we can find the total surface area by adding the lateral surface area and the base area:
Total surface area = Lateral surface area + Base area
= 125.6 + 78.5
= 204.1 square meters
Rounded to the nearest tenth, the surface area of the cone is approximately 204.1 square meters, not 287.12 square meters.
Lateral surface area = π × r × l
where r is the radius and l is the slant height.
Using the given values, the lateral surface area is:
Lateral surface area = 3.14 × 5 × 8 = 125.6 square meters (rounded to the nearest tenth)
The formula for the area of the base of a cone is given by:
Base area = π × r^2
Using the given radius, the base area is:
Base area = 3.14 × 5^2 = 78.5 square meters
Now, we can find the total surface area by adding the lateral surface area and the base area:
Total surface area = Lateral surface area + Base area
= 125.6 + 78.5
= 204.1 square meters
Rounded to the nearest tenth, the surface area of the cone is approximately 204.1 square meters, not 287.12 square meters.

Apologies for the incorrect response.
To find the surface area of a cone, we need to calculate the lateral surface area (including the curved surface area) and the base area.
The formula for the lateral surface area of a cone is:
Lateral surface area = π × r × l
where r is the radius and l is the slant height.
Using the given values, the lateral surface area is:
Lateral surface area = 3.14 × 5 × 8 = 125.6 square meters
The formula for the base area of a cone is:
Base area = π × r^2
Using the given radius, the base area is:
Base area = 3.14 × 5^2 = 78.5 square meters
Now, we can find the total surface area by adding the lateral surface area and the base area:
Total surface area = Lateral surface area + Base area
= 125.6 + 78.5
= 204.1 square meters
Therefore, the correct surface area of the cone is approximately 204.1 square meters. Apologies for any confusion caused.
