redoing my calculations, i got this: it doesnt seem reasonable though

A) B) F1/A1 = F2/A2 + pgh (F1/A1 = F2/A2 + pgh)(A1 * A2) multiply both sides by A1 and A2 to cancel out the denominator that gives: A2F1 = A1F2 +A1A2(pgh) subtract A1A2(pgh) from both sides: A2F1 - A1A2(pgh) = A1F2 factor out A2: A2(F1 - A1(pgh)) = A1F2 divide both sides by (F1 - A1(pgh))...

I solved for part A by using the equation r2 = sqrt(m2/m1) * r1 im having trouble solving for part B, I know that you would use the equation F1/A1 = F2/A2 + pgh and solve for r2, but when I solved for r2, I got an undefined number. Can someone run me through this question?
