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.

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

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

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

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

@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?

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
