Question

Pre-Algebra help please! Medal will be awarded! :-)

Answer 1

Lateral Area of Cylinder = 2*pi*r*h where r = base radius and h = height

LA = 2 * pi * 6 * 24

LA = 48 * 6 * pi

LA = ?

Answer 2

L = 2(pi)rh
r = 6
h = 24
pi = 3.14

L = 2(3.14)(6)(24)

can you do it from here ?

Answer 3

To the nearest whole number, 904 yd^2 would be correct.

Answer 4

It's going to be the Lateral Area formula + 2 B where B is the area of the base.

Answer 5

TA = 2 * pi * 6 * 20 + 2* pi* 6^2

Answer 6

Is that 312 pi?

Answer 7

surface area = 2(pi)r^2 + 2(pi)rh
pi = 3.14
r = 6
h = 20

Answer 8

No matter what I try, I am not getting any of your answer choices. This is driving me crazy.

Answer 9

Answer 10

possibly...can't make no promises that I will know how to do it

Answer 11

Would you check and see if these options go with that green cylinder problem?
180 ft^2
720 ft^2
433 ft^2
135 ft^2

I keep getting 980

Answer 12

Here is my green prism equation:

TA = 2 * pi * 6 * 20 + 2* pi* 6^2

Answer 13

Red Prism:

LA = ph where p is the perimeter of the base and h is the height

Answer 14

LA (Red) = (2*15 + 2*6) * 26

Answer 15

your good :)

Answer 16

Thats what I got on the first one

Answer 17

I see it right here among the options: Find the lateral area for the given prism.

1,092 cm^2---->
998 cm^2
1,272 cm^2
870 cm^2

Answer 18

It is a good idea not to place two problems in one thread. :)

Answer 19

I must have done the first one wrong because the answer I am getting is not a choice

Answer 20

lets do it Directrix's way....
A = 2 * pi * 6 * 20 + 2 * pi * 6^2
A = 2 * 3.14 * 6 * 20 + 2 * 3.14 * 36
A = 753.60 + 226.08
A = 979.68

What am I doing wrong ?

Answer 21

I keep getting this answer ?????

Answer 22

get Directrix back here....

Answer 23

I'm sorry I couldn't really help you

Answer 24

medal should go to directrix

Answer 25

let me know...I am curious

Answer 26

I don't know....

Answer 27

good idea...find out what we did wrong

Answer 28

lol.....thanks.....good night

Answer 29

Is something still not right here? If so, which one?

Answer 30

the first one.....the green prism.....we keep getting 979.68 and the answer that sadieK said she checked and the answer is 433. I can't figure out what I did wrong ?

Answer 31

She seems to have deleted a lot of her posts

Answer 32

Directrix....can you tell me what I did wrong ?

Answer 33

@kelliegirl33 I am totally confused on which cylinder and which set of options we are doing.

Answer 34

I looked over here and could not find the diagram or anything.

Answer 35

Here is my green prism equation:

TA = 2 * pi * 6 * 20 + 2* pi* 6^2

Answer 36

980.18

Answer 37

Thats not even one of the answer choices she gave. I am not even gonna worry about it anymore....sadieK doesn't seem to be worried and it is her problem. She deleted everything we worked on including the diagrams. You deserved the medal for this...not me...so I am gonna give you a medal :)

Answer 38

Thanks. It would be great to get resolution on the problem but it is not here.
Alrighty then.
