What is the approximate outer surface area of one of these hats that has a radius of 9 inches and a slant height of 12 inches? Keep in mind that there is an opening in the hat where the base surface would normally be. Show the steps of your solution and explain your work.

The surface area of a cone (excluding the base) is pi*r*s, where r = radius and s = slant height
So in this case, we have pi*9*12 = 96*pi =~ 301.59 in^2
