I pity you for having to solve that problem. It's as foreign as the lady in it!

- anonymous

That was his way of saying he doesn't know how to help you.

- anonymous

@blueweek77

- anonymous

I wish i could, but i know that @ganeshie8 probably could :D

- anonymous

ok thanks

- anonymous

@ganeshie8 can you help me please

- anonymous

Well, let's go through this step-by-step

- anonymous

What shape is the hat?

- anonymous

are you there? @chloeismyname3

- anonymous

The hat is in the shape of a cone

- anonymous

this is your equation
A2 = 2RH - H2

- anonymous

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

- anonymous

Sorry, wrong one
2(pi)RH

- anonymous

A = 3.14(9)(12)

- anonymous

A = 339.12

- anonymous

339.12 in^2

- 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

your answer is incorrect

- anonymous

Somehow you solved the equation wrong

- 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

Huh, it's still there, but some of my older replies were replicated and posted again. WTF, Openstudy??!!

- anonymous

So what would I have to change?

- anonymous

wait...what?sorry, you multiplied 9 x 12 incorrectly

- anonymous

it's 108, not 96

- anonymous

108 x pi(3.14) = 339.12

- anonymous

oh ok thanks

- anonymous

I just told you...what are you confused about?

- anonymous

OMG OPENSTUDY :|

- anonymous

ikr, it sucks

- anonymous

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

- anonymous

You had multiplied 9 x 12 incorrectly

- 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

exactly

- anonymous

You had originally gotten 309 or something, hence why we had to go through this :)

- anonymous

Ok Thank you so much. Yeah that was just a typo sorry lol

- anonymous

yw, np :)
