Answer:

Using the formula for the surface area of a cone, we find that the surfaace area of this cone is 115.2π m².

Step-by-step explanation:

The formula for the surface area of a cone is πrl + πr², where -

- r is the radius

- l is the slant length

This cone has a radius of 6.4 meters and a slant length of 11.6 meters. Plugging these values into the equation, we get:

[tex]A = \pi * 6.4 * 11.6 + \pi*6.4^2\\A = \pi*74.24+\pi*40.96\\A=115.2\pi[/tex]

So, the cone has a surface area of 115.2π m².
