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 pl and round to the nearest tenth, if necessary. (1 point)

Question

square meters

Answer 1

The formula for the surface area of a cone is given by A = πr(r + l), where A is the surface area, r is the radius, and l is the slant height.

Using the given values, we have:

A = π * 5 * (5 + 8)
A ≈ 3.14 * 5 * 13
A ≈ 3.14 * 65
A ≈ 204.1

So, the surface area of the cone is approximately 204.1 square meters.
