Question

Quick 'formula'question!

Solve for the variable *a* in this equation.
c= 8πfb (It doesn't even list an 'a' either. o-o)
A.)8πbc=f
B.)c/8 =f
C.) c/8π =f
D.) c/8πb =f

Help?? XD

Answer 1

I assume you needs to solve for the variable f?

Answer 2

I suppose I do lol

Answer 3

Because, thats what they did in the answers, that you can select :P

Answer 4

Ohh I see, I feel stupid for that. But I don't exactly know what I'm doing here

Answer 5

You need to isolate f. So in order to get rid of 8πb on the right side then you need to divide both sides with it.

Answer 6

So i divide both sides by 8πb? (Just making sure I don't do something else incorrectly xD)

Answer 7

Yes :)

Answer 8

Try and to that, and tell me what answer you get

Answer 9

So then that'd be... 8 times 3.14 which is 25.12. But what do I do with the b?

Answer 10

You dont have any values for c or b. So you just want to isolate f:\[c=8πfb\]\[\frac{ c }{ 8πb }=f\]

Answer 11

This looks exactly like one of your answer, which?

Answer 12

Oh so then it's just D? That was simpler than I thought

Answer 13

Correct :)
D.) c/8πb =f

Answer 14

Thanks! :D

Answer 15

You're welcome :)
