The surface area of a cone is given by the formula:
Surface Area = π * r * (r + s)
where r is the radius and s is the slant height.
Given that the radius is 5 meters and the slant height is 8 meters, we can substitute these values into the formula:
Surface Area = 3.14 * 5 * (5 + 8)
Simplifying this expression, we get:
Surface Area = 3.14 * 5 * 13
Surface Area = 204.1 square meters
Rounding to the nearest tenth, the surface area of the cone is 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)
