OpenStudy (i_love_my_nieces):

Those are my questions.

OpenStudy (majesty69):

First do you know the equations?

OpenStudy (majesty69):

Sorry not equations....formulas

OpenStudy (i_love_my_nieces):

The formulas you mean? And yes.

OpenStudy (i_love_my_nieces):

Sorry you already corrected yourself

OpenStudy (majesty69):

Give me a sec

OpenStudy (i_love_my_nieces):

Lateral Area: AL = (a + b + c)h Volume: V = πr^2h Surface Area: A = πr(r + 'square root'h^2 +r^2)

OpenStudy (i_love_my_nieces):

Why did you leave

OpenStudy (majesty69):

Sorry i had to close out my computer was being stupid lol

OpenStudy (i_love_my_nieces):

It's okay

OpenStudy (majesty69):

Okay so now you need to plug in the numbers to those formulas. For example for the cylinder you would first find the radius.

OpenStudy (i_love_my_nieces):

Here is what I got

OpenStudy (i_love_my_nieces):

AL = 528 V = 24513.85 A = 151.58

OpenStudy (majesty69):

Okay let me check

OpenStudy (i_love_my_nieces):

Okay.

OpenStudy (i_love_my_nieces):

** V = 351.68

OpenStudy (majesty69):

Volume = 24513.85 CORRECT SA = I got 138.23 LA = I got 352

OpenStudy (i_love_my_nieces):

1.) Formula: LA = (a + b + c)h Work: Answer: 2.) Formula: V = πr^2h Work: Answer:

OpenStudy (i_love_my_nieces):

Can you fill in the Work and Answer part to make use I have it right

OpenStudy (i_love_my_nieces):

@Majesty69 can u

OpenStudy (majesty69):

Yeah

OpenStudy (i_love_my_nieces):

Thanks

OpenStudy (i_love_my_nieces):

Wait don't forget about the third one. I will brb my mom called me. Just do what I asked you to, please

OpenStudy (i_love_my_nieces):

I'm back did you do it yet?

OpenStudy (majesty69):

V = \[\pi17^{2}27\] = 7803pi = 24513.85

OpenStudy (i_love_my_nieces):

What about the other two?

OpenStudy (majesty69):

im working on the others

OpenStudy (majesty69):

A = 138.23m^2 for the cone LA = 352 m^2 for the pyramid you're going to have to show the work but those are the answers

OpenStudy (i_love_my_nieces):

How am I going to show the work if I don;t know how you got the answer

OpenStudy (i_love_my_nieces):

@Majesty69

OpenStudy (majesty69):

I gave you the answers to check them...now use the formulas until you can figure out how to get it and get the same answers.

OpenStudy (i_love_my_nieces):

Okay. Can you stay online so you can check my answers

OpenStudy (majesty69):

i have to take a test so delayed answers should be expected hahaha

OpenStudy (i_love_my_nieces):

How long do you think it will take you to do the test?

OpenStudy (i_love_my_nieces):

Idk how you got 352 m^2 on the lateral area one

OpenStudy (majesty69):

Well that is what i got if it was wrong I'm sorry but i calculated it multiple time
