SOLUTION: How do I solve the following equation for "f"? a=(2pirf)^2/r This is how far I got: a=4pi^2r^2f^2/r a=4pi^2rf^2 a/4pi^2r=f^2 If this is correct so far, where do I

You can put this solution on YOUR website!
a=(2pirf)^2/r
:
This is how far I got:
a=4pi^2r^2f^2/r
a=4pi^2rf^2
:
At this point just divide both sides by 4*pi^2*f^2 which leaves you with
= r
:
you could also write it:
r =
:
Student pointed out to me that I should have solved for f not r:
a =
:
Divide both sides by (4*pi^2*r) and you have:
= f^2
:
f =
:
You can also write it:
f =
