Question

Solve for R.
C=1/9π n^2r

Answer 1

For this, you are going to use natural log to solve for r.
I am going to assume that your function looks like this:
\[\frac{ 1 }{ 9 }\pi n^{2r} = C\]
Follow these steps:
1. multiply
2. divide
3. take the natural log
[NOTE: \[\ln(a)^P=pln(a)\]
From this point, you should be able to solve use the algebra tricks similar to the previous steps to solve for 'r'.
Let me know if you get stuck.

Answer 2

The r is suppose to be regular not up by the small 2

Answer 3

is that the question?\[C=\frac{1}{9}π n^2r\]

Answer 4

yes

Answer 5

\[C=\frac{1}{9}π n^2r\]
multiply both by 9

\[9*C=\frac{1}{9}π n^2r*9\]
\[9*C=π n^2r\]
divide both sides by π n^2
\[\frac{1}{π n^2}9C=\frac{1}{π n^2}π n^2r\]
\[\frac{1}{π n^2}9C=r\]
\[\frac{9C}{π n^2}=r\]
