Answer 3

I'm not sure if any of you guys know how to do this, but I'm very stuck.

Answer 4

Do you know the area formula for a cylindar?

Answer 5

2πrh is the formula

Answer 6

No.

Answer 7

But I did just google it, so I know a little bit about it now.

Answer 8

2* pi * r * h + 2 * pi * r^2

Answer 9

\[A = \pi rh +2 \pi r\]

Answer 10

ya, do you know where to plug in the numbers to solve?

Answer 11

No

Answer 12

3.14 * 5 (I think) * 9 ... maybe?

Answer 13

I'm not sure...

Answer 14

You know I"m not entirely sure how to do this...the shape isn't even in the form of a cylinder.... @e.mccormick do you know how to do this?

Answer 15

@midhun.madhu1987 how about you?

Answer 16

5 is the radius so what is 9? the height?

Answer 17

yes it's the height I think.

Answer 18

This is stressing me out lol.

Answer 19

so the answer i know should be AL≈282.74 don't know how to explain it though
its stressing -.-

Answer 20

it's supposed to be in inches^2 but I don't know.

Answer 21

oh I'm supposed to express it in pi as well.

Answer 22

yup its stressing its been years since i did this um my teacher taught me like this, i wasn't patient
AL=2*pi*r*h

Answer 23

its unfolded so its easier the cyclinder

Answer 24

I don't know what to do.

Answer 25

look solve this
2(3.14)(5)(9)

Answer 26

that's 282.6

Answer 27

i got 282.6 in sq. sone if its just the lateral you need to find

Answer 28

is there a formula for that?

Answer 29

yea what i had said earlier AL=2*pi*R*H

Answer 30

so 2 * 3.14 * 5 * 9?

Answer 31

@Crissy15

Answer 32

yup

Answer 33

324.99 so then would I divide that by pi?

Answer 34

The answer you had before was your answer 282.6 inches squared, but if you also needed to find the surface area then thats a whole different story. I had posted a video all the way up top, that explains what I did.

Answer 35

but it has to be in terms of pi. So would I then divide 282.6 by pi
