-A can in the shape of a right circular cylinder is required to have a volume of 700 cubic centimeters. The top and bottom are made up of a material that costs $8 \%$ per square centimeter, while the sides are made of material that costs 5 e per square centimeter. Which function below describes the total cost of the material as a function of the radius $\mathrm { r }$ of the cylinder?

A) $\mathrm { C } ( \mathrm { r } ) = 0.16 \pi \mathrm { r } ^ { 2 } + \frac { 140 } { \mathrm { r } }$
B) $C ( r ) = 0.08 \pi r ^ { 2 } + \frac { 70 } { r }$
C) $\mathrm { C } ( \mathrm { r } ) = 0.16 \pi \mathrm { r } ^ { 2 } + \frac { 70 } { \mathrm { r } }$
D) $C ( r ) = 0.08 \pi r ^ { 2 } + \frac { 140 } { r }$
