Answer:
independent
Step-by-step explanation:
Dependent equations graph as the <em>same line</em>. These lines are not the same, so the equations are independent.
___
However, the lines are parallel, so the equations are also <em>inconsistent</em>. There is <em>no solution</em> to this system of equations.
S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)
