A student put a sucrose solution into dialysis tubing and tied off both ends. As a result, a cylinder was formed with a length of $5.0\ \text{cm}$ and a radius of $2.0\ \text{cm}$. What is the surface area to volume ratio for this cylinder of dialysis tubing?
- A$0.7 : 1.0$
- B$1.0 : 1.0$
- C$1.4 : 1.0$
- D$2.5 : 1.0$
