Question

How do you calculate the area of a cone?

Answer 1

depends on how you are defining area

Answer 2

perl, did you get a pm or a notification?

Answer 3

Surface area I'm assuming?

Answer 4

Yes I did

Answer 5

Iambatman, did you get a message too?

Answer 6

@Preetha just a quick question why is your post blue?

Answer 7

which?

Answer 8

Nope, I just saw a question and came gliding.

Answer 9

its a qualified helper question

Answer 10

Because I paid to get a qualified helper.

Answer 11

I got a notification and

Answer 12

nice

Answer 13

a message popped up near the mailbox, but it didnt actually send a pm

Answer 14

okay, let me teach you how to obtain the area of any cone

Answer 15

wait can regular users respond to people that have paid to get help too?

Answer 16

Ninc, did you get a notification too?

Answer 17

yes

Answer 18

Anyone can respond.

Answer 19

Nice job.

Answer 20

I don't think that should be acceptable. let's say you ask a QH question, and no QH helps, but regular users help.You just wasted some owlbucks :(

Answer 21

exactly @sammixboo

Answer 22

That is a good point..

Answer 23

$$\Large
SA=\pi r^2+\pi r \sqrt{r^2+h^2}

$$

Answer 24

Nice Latex Perl

Answer 25

I mean, maybeeeeee keep it open to everyone until you get more qualified helpers

Answer 26

But that is what I think

Answer 27

sammi is so smart

Answer 28

she gets the message out lol

Answer 29

@nincompoop using caclulus?

Answer 30

breaking from volume to area

Answer 31

calc*

Answer 32

No calculus.

Answer 33

fine then let us just memorize formulas :)

Answer 34

is there any other way to derive it without calculus hehe

Answer 35

Wow. I love this. Getting Perl and Ninc to help me understand this.

Answer 36

i believe there :)

Answer 37

with cone, most probably, but not with any irregular shapes

Answer 38

is*

Answer 39

So you can't do this without calculus. I could live with a little calculus I suppose.

Answer 40

we can do without calculus

Answer 41

You can

Answer 42

We can derive the formula for the surface area. First cut the cone , you will get this figure.

Answer 43

he has so many people on here and there's other people who need help besides him. just saying

Answer 44

i think there is some kind of approach, after all people knew it before calculus

Answer 45

what we do is focus on the area of the base

Answer 46

Awesome. I do thank you for helping test this out. All is clear now.
