Well, let's go through this step-by-step
anonymous
  • anonymous
What shape is the hat?
anonymous
  • anonymous
are you there? @chloeismyname3
anonymous
  • anonymous
The hat is in the shape of a cone
anonymous
  • anonymous
this is your equation A2 = 2RH - H2
anonymous
  • anonymous
A^2 = 2(9)(12) - (12)(2)
anonymous
  • anonymous
Sorry, wrong one 2(pi)RH
anonymous
  • anonymous
A = 3.14(9)(12)
anonymous
  • anonymous
A = 339.12
anonymous
  • anonymous
339.12 in^2
anonymous
  • anonymous
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
anonymous
  • anonymous
....
anonymous
  • anonymous
your answer is incorrect
anonymous
  • anonymous
Somehow you solved the equation wrong
anonymous
  • anonymous
how is it wrong?

Gah, wtf is up with OpenStudy. It is way to glitchy....hope you saw my response before it was deleted
anonymous
  • anonymous
Huh, it's still there, but some of my older replies were replicated and posted again. WTF, Openstudy??!!
anonymous
  • anonymous
So what would I have to change?
anonymous
  • anonymous
wait...what?sorry, you multiplied 9 x 12 incorrectly
anonymous
  • anonymous
it's 108, not 96
anonymous
  • anonymous
108 x pi(3.14) = 339.12
anonymous
  • anonymous
oh ok thanks
anonymous
  • anonymous
I just told you...what are you confused about?
anonymous
  • anonymous
OMG OPENSTUDY :|
anonymous
  • anonymous
ikr, it sucks
anonymous
  • anonymous
one last try... 9 x 12 = 108 108 x 3.14 = 339.12
anonymous
  • anonymous
You had multiplied 9 x 12 incorrectly
anonymous
  • anonymous
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
anonymous
  • anonymous
exactly
anonymous
  • anonymous
You had originally gotten 309 or something, hence why we had to go through this :)
anonymous
  • anonymous
Ok Thank you so much. Yeah that was just a typo sorry lol
anonymous
  • anonymous
yw, np :)
