V=Nh^2(r-h/3) make r the subject of the formular
To make "r" the subject of the formula: V = Nh^2(r - h/3)
Step 1: Expand the equation:
V = Nh^2r - Nh^3/3
Step 2: Move the term containing the "r" variable to one side of the equation:
Nh^2r = V + Nh^3/3
Step 3: Divide both sides of the equation by Nh^2:
r = (V + Nh^3/3) / Nh^2
Step 4: Simplify the expression on the right-hand side if necessary.
And that's how you can make "r" the subject of the formula.
Nh^2(r-h/3) = V
r - h/3 = V/(Nh^2)
now finish it off
