Solve for the variable r in this equation: s = 2πrh
2 answers:
R = S/2πh
<span>2) V= πr^2h, for variable h </span>
<span>Same procedure in this one </span>
<span>Divide both sides byπr^2 </span>
<span>V/πr^2 = h </span>
<span>h = V/πr^2 </span>
S = 2(pi)rh.....divide both sides by 2(pi)h
s / (2(pi)h = r
