Answer 9

@.Sam.

Answer 10

What exactly is the problem?

Answer 11

I see I don't have area = 33.284 mm or ? is that find for area?

Answer 12

What does the problem ask you to do?

Answer 13

Are you trying to find the volume of a nickel coin?

Answer 14

also that too yes

Answer 15

My two biggest questions are; 1. Did I mark them correctly by either using mm or nothing or cm^2 etc?
2. 12oz can BIG trouble figuring out area, surface area and volume : (

Answer 16

it's really unclear what you are asking me here. Please, state the exact question, and what you want me to do.

Answer 17

finally got my attachment up!

Answer 18

ok maybe I am thinking it's wrong, but it's not : )

When I have the area 33.284 and the circumference of that object is in mm was I suppose to put 33.284mm or just the number?

Answer 19

area is 2 dimensional, right?

Answer 20

basically are all my mm, cm^3, cm^2 etc correct and labeled?

Answer 21

you compute area of a rectangle as length * width, so the units should match. 3 mm * 5 mm = 15 mm^2

Answer 22

did you see my attachment?

Answer 23

ok yes, so it should be mm^2?

Answer 24

no, it hasn't downloaded.

Answer 25

computer hates me

Answer 26

ok but you answered one of my questions. : ) Let me show you my 12oz can one just sec

Answer 27

or perhaps it hates me. just got it to download on my iPad.

Answer 28

Wait! I have surface area for quarter 4.622 sq centimeters and Volume 811.6 cubic meters and circumference and area in mm

Answer 29

Yeah!! :)

Answer 30

I feel like I have it all mixed up on some. I think my rectangular prisms are good and done. But my cylinders are messed up.

Answer 31

okay, this is kind of a mess. for the nickel, you have the right circumference (and unit). The area has no units and the number is wrong. surface area I get a slightly different number (839 mm^2 which corresponds to 8.39 cm^2) but maybe my height is different
volume looks okay
for the quarter, circumference is ok, area is wrong, surface area looks wrong
don't have dimensions for a 12 oz can but volume is okay (you read the label :-)

Answer 32

area is wrong for dime (and no unit), surface area is wrong (and wrong unit), volume is okay
for penny, area is wrong, surface area is wrong and wrong unit, volume is approximately right but has wrong unit

Answer 33

ohh ok I need to work on these. I need help : (

Answer 34

I understand NO units for area are needed to put down right?

Answer 35

I have to go to the store with my mom I will be right back if your back? : ( I have to turn this in tonight.

Answer 36

I won't close this yet, but I need to delete my school work so no one copies. or if anyone can help asap? That 's here? @eSpeX @smokeydabear @amistre64 @whpalmer4

Answer 37

why would you think area doesn't require units?

Answer 38

sorry I thought you meant don't put units but you meant there are NO units showing for each area.

Answer 39

Looks like I have to recalculate my stuff asap. How are my rectangular prisms measurements? On the bottom? @whpalmer4
