A=4ℼR2 solve for R
SHOW ALL STEP

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

f(x) is going down by 4
