this is your equation
A2 = 2RH - H2
HourglassMage
Best Response

A^2 = 2(9)(12) - (12)(2)

Sorry, wrong one
2(pi)RH

nevermind i figured out the answer, but I will still give you a medal for helping thanks :)
This is what I got
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

it's 108, not 96
HourglassMage

108 x pi(3.14) = 339.12

one last try...
9 x 12 = 108
108 x 3.14 = 339.12

it would be
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 = 108*pi =~ 339.12 in^2
