I hope the pictures are clear and you get the concept!
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
