Eight Resistances Are Connected in Series as Shown $$C = \frac { k d } { A }$$

Eight resistances are connected in series as shown. The unit of measure for resistance is the ohm. The resistance in a series circuit is the sum of all resistances in that circuit. Find the total amount of resistance in the circuit. $$C = \frac { k d } { A }$$

A) $C = \frac { k A } { d }$
B) $C = \frac { k } { d A }$
C) $C = \frac { d } { k A }$
D) $4~~7 / 59 ~~\Omega$
