Simplifying rA = 2pirh Solving rA = 2hipr Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-2hipr' to each side of the equation. -2hipr + rA = 2hipr + -2hipr Combine like terms: 2hipr + -2hipr = 0 -2hipr + rA = 0 Factor out the Greatest Common Factor (GCF), 'r'. r(-2hip + A) = 0Subproblem 1
Set the factor 'r' equal to zero and attempt to solve: Simplifying r = 0 Solving r = 0 Move all terms containing r to the left, all other terms to the right. Simplifying r = 0Subproblem 2
Set the factor '(-2hip + A)' equal to zero and attempt to solve: Simplifying -2hip + A = 0 Reorder the terms: A + -2hip = 0 Solving A + -2hip = 0 Move all terms containing r to the left, all other terms to the right. Add '-1A' to each side of the equation. A + -1A + -2hip = 0 + -1A Combine like terms: A + -1A = 0 0 + -2hip = 0 + -1A -2hip = 0 + -1A Remove the zero: -2hip = -1A Add '2hip' to each side of the equation. -2hip + 2hip = -1A + 2hip Combine like terms: -2hip + 2hip = 0 0 = -1A + 2hip Simplifying 0 = -1A + 2hip The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
