Question

Evan is painting a stool that has a cylindrical seat and four rectangular prism legs. The seat has a diameter of 8 inches and a height of 2 inches. Each leg is 2 inches by 2 inches by inches. How much area will Evan have to paint? Use for . Show your work.

Answer 1

plz help

Answer 2

>> Is this " Each leg is 2 inches by 2 inches by inches" supposed to be 2 by 2 by 2 or something else?

Answer 3

If the stool is already assembled, then Evan will not be able to paint the surface of each leg that is attached to the stool, I assume.

And, do you @Amandawalden123 think that Evan will paint the surface of each leg where the leg touches the floor. We need to know that for the area of the stool legs which will be painted.

And, do you think we will be painting the underside of the cylindrical stool?

If you have a diagram, please post it. If not, we'll have to make some assumptions about what Evan is painting and go from there.

Answer 4

@Amandawalden123 Do you have a diagram of the stool? Yes or No?

We need to get to work.

Answer 5

no

Answer 6

i dont have a diagram

Answer 7

Well, Evan has been doing a lot of painting as you see on the attachment. So, we will not paint where the legs touch the floor or attach to the seat.

Answer 8

ok

Answer 9

Look at the problem as written in your text.

Tell me what is the missing dimension of the leg.

Read what you posted: 2 inches by 2 inches by ???? inches.

What is ??? supposed to be? That is holding us up. @Amandawalden123

Answer 10

it would be by 4 inches ?

Answer 11

Is 4 the number given in the problem in your text. This is not something that we can compute or guess. Does this --. >> it would be by 4 inches ?
mean that the legs are 2 by 2 by 4 or that you "think" the legs are 2 by 2 by 4?

Answer 12

i was thinking it was 2 by 2 by 4

Answer 13

Surface Area of Cylinder:

SA = 2*π*r*h + 2B where r is the radius of the stool seat and 2 is the height of the seat. B is the area of the circular base of the seat.

SA (seat) = 2*π*4*2 + 2*π*4*4

Your Task @

Crank out what this equals": 2*π*4*2 + 2*π*4*4

--------------
Another part of the question was not posted: Use for . Show your work.

What do we use for pi: 3.14 ?

Answer 14

@Amandawalden123

Crank out what this equals": 2*π*4*2 + 2*π*4*4
Use 3.14 for pi, I assume.

While you do that, I will work on the legs.

Answer 15

ok

Answer 16

Lateral Area of a rectangular prism (leg) excluding two bases.

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

LA (one leg) = (2+2+2+2)*4 = 32 square inches.

There are 4 legs so
the total lateral area of the 4 legs is 32*4 = 128 square inches. -->

Answer 17

i having a little bit of trouble

Answer 18

im

Answer 19

Let's break up what you are calculating:

2*π*4*2 + 2*π*4*4
==============


What is 2* 3.14 * 4 * 2 -> What is this product
if you multiply 2 times 3.14 times 4 times 2 --> @Amandawalden123

Use your calculator or the Google calculator.

Answer 20

ok

Answer 21

i got 50.24

Answer 22

Good.

Now, enter this in the Google search box or your calculator:

2*π*4*4 which is 2*3.14*4*4 =" --> @Amandawalden123

Post what you get.

Answer 23

i got 200.96

Answer 24

Not correct for this: 2 * 3.14 * 4 * 4 =

That is 2 times 3.14 times 4 times 4.

Try again.

Answer 25

Are you using the Google calculator, your own mechanical calculator, or the calculator on your neck. Any will do.

Answer 26

mechanical calculator

Answer 27

my own

Answer 28

I don't know what's up:

2 times 3.14 times 4 times 4 =

6.28 times 4 times 4 =

6.28 times 16 =

100.48

Answer 29

Now, add 100.48 and 50.24. What is that sum? That will be the stool which was this: 2*π*4*2 + 2*π*4*4.

Answer 30

oh i did it all at once i went 2 x 3.14 x 4 x 4

Answer 31

That should work but I do not know the operating system of your mechanical calculator. Just use the one on your neck. :)

Answer 32

ok

Answer 33

Still waiting for this: add 100.48 and 50.24 = ? ------>

Answer 34

oh sorry i got 150.72

Answer 35

is that right

Answer 36

That is the total area of the cylindrical seat. That includes the bottom of the seat where the legs attach.

Answer 37

Once again, here is my leg work:

Lateral Area of a rectangular prism (leg) excluding two bases.

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

LA (one leg) = (2+2+2+2)*4 = 32 square inches.

There are 4 legs so the total lateral area of the 4 legs is 32*4 = 128 square inches. -->

Answer 38

Assuming that is correct, add 128 and 150.72. What is that sum?

Answer 39

>is that right I do not know because I am waiting for you to find the sum.

128 and 150.72. What is that sum? ---> @Amandawalden123

Answer 40

ok

Answer 41

>>is that right I do not know because I am waiting for you to add 128 and 150.72

Answer 42

i still multiply right

Answer 43

ADD 128 and 150.72. Do 128 PLUS 150.72

Answer 44

I got 278.72 square inches. What did you get? @Amandawalden123

Answer 45

ok i got 278.72

Answer 46

what else do you need me to do because i suck a math

Answer 47

I cannot see the main page of OpenStudy. Can you?
Yet, I went to my Profile Page and looked at "Questions Answered" to find the thread where we were working.

As far as I know, this stool problem is finished.

Answer 48

ok im still here :)

Answer 49

@Amandawalden123 Did you check the answer to the problem?
Recall that this is what we got: 278.72.
