Question

Gina stores her toys in a container which has a cylindrical body and a conical lid, as shown below.



She wants to cover the entire exterior portion of the container with paper. How much paper, in square feet, would Gina need?

Answer 1

16 right?

Answer 2

you need to find the lateral area. i dont have the formulas with me but after finding the la for both, you add them.

Answer 3

for both what?

Answer 4

well then it's 16...

Answer 5

what about the pi? did you round that in?

Answer 6

area of cylindrical part = pi*2^2 + 3 * 2*pi*2

Answer 7

50.26548245743669?

Answer 8

That's not a choice though ;/

Answer 9

area of cone part = pi*2*2
- though this isn't possible - slant height cannot be equal to radius of the base

Answer 10

eh...?

Answer 11

answer is 16?

Answer 12

This one is better

Answer 13

what does n mean..

Answer 14

it is supposed to be pi

Answer 15

area of cylinder = what you said
take a look - the radius of base of cone = 2 and the sloping side = 2 - not possible

if you take it as it is this area = 4 pi
making total about 62.83

Answer 16

16π
20π
24 π
28 π
But these are the answers ;/

Answer 17

you dont use area, it says "She wants to cover the entire exterior portion"

Answer 18

so it's 24?

Answer 19

Cylinder:
2πrh
2π(2)(3)
12π

Cone:
πrl
π(2)(2)
4π

4π+12π=16π

16π

Answer 20

that's all i ask for xD thanks

Answer 21

No problem :-)

Answer 22

u understand it now, since it asks for exterior... you have to find lateral area not area. all you really need is the formula and youre done

Answer 23

i mean not volume or surface area
