Given problem;
A = 4 π R²
To solve for R, we have to make it the subject of the expression.
Since
A = 4 π R² , follow these steps to find R;
Multiply both sides by 
A x = x 4 π R²
= R²
Then find the square root of both sides
√R² = 
R =
The solution is
Well we know that every 2 eggs requir 1 and 3/4 of flour so the easiest thing to do here (for me at least) is to round the fraction to the nearest whole number which in this case will be 1. Now that that's done we can say every 2 eggs calls for 2 cups of flour. Now all you need to do is multiply 2 by 9 to get 18 then put that in fraction form it'll be 17 and 3/4 cups of flour. I hope this helps!
