What do know about this question? Is there anything in general you need help on?
OpenStudy (ineedhelponhw):
I forgot how to do it. Its been years
OpenStudy (ineedhelponhw):
And its the only question I have so I can get my other homework done.
JoelTheBoss (joel_the_boss):
\[4*\pi(30*10^{-2})^2\]
This is the equation correct?
OpenStudy (ineedhelponhw):
Ye it is I did what i could remeber

ok would you like me to solve it for you? Step by step?
OpenStudy (ineedhelponhw):
Yes please so I can get other questions like that.
OpenStudy (ineedhelponhw):
I can solve bymyself
OpenStudy (ineedhelponhw):
laster on
JoelTheBoss (joel_the_boss):
What are asking for exactly? Another equation similar to this one?

They want the total surface area of the satellite which you know has a diameter of 60cm
OpenStudy (ineedhelponhw):
And they gave us the hint of the surface area 4pir^2
JoelTheBoss (joel_the_boss):
ok then you solve the equation I gave you to get the answer. :)
OpenStudy (ineedhelponhw):
O
JoelTheBoss (joel_the_boss):
Would you like me to do it? Or are you ok..

May you please.
OpenStudy (ineedhelponhw):
I want to know step by step so I can later on.
JoelTheBoss (joel_the_boss):
typo
OpenStudy (ineedhelponhw):
o ok
JoelTheBoss (joel_the_boss):
First we can simplify the equation to look like \[4*(\pi(30*10^{-2}))\]

OpenStudy (ineedhelponhw):
Okay.
OpenStudy (ineedhelponhw):
We have to simplify diameter right? so that's why it's 30
JoelTheBoss (joel_the_boss):
The next step would be to write \[30*10^{-2}\]In Proper Scientific Notation. \[4*(\pi(3*10^{-1}))\]
OpenStudy (ineedhelponhw):
Okay.
JoelTheBoss (joel_the_boss):
Next we convert \( 30*10^{-1}\) from scientific notation \(4*(pi*0.3)\)

Then we Multiply \(pi\) by 0.03 to get \[0.9424778\]Next just plug the 4 back in, \(4*0.9424778\)
JoelTheBoss (joel_the_boss):
Can you do the rest or do you want me to do it?
OpenStudy (ineedhelponhw):
You do it please
JoelTheBoss (joel_the_boss):
ok :)
JoelTheBoss (joel_the_boss):
The Last step is just to times
\(4*0.9424778\)
The final answer would be,
\(3.76991118\)
Hope I helped. :)
