The formula for the surface area of a cone is given by:
Surface Area = π * r * (r + l),
where r is the radius and l is the slant height.
Plugging in the given values, we have:
Surface Area = 3.14 * 5 * (5 + 8)
= 3.14 * 5 *13
= 204.1.
Therefore, the surface area of the cone is approximately 204.1 square meters.
What is the surface area, in square meters, of a cone with a slant height of 8 meters and a radius of 5 meters? Use 3.14 for pi and round to the nearest tenth, if necessary. (1 point)
