The electron micrograph displays rod-shaped bacteria. The bacterium has an actual length of $2.0\,\mu\text{m}$ and a diameter of $0.5\,\mu\text{m}$. Suppose the bacterium is cylinder-shaped. Calculate the surface area to volume ratio of the bacterium?
- A$3.0 : 1.0$
- B$5.0 : 1.0$
- C$8.0 : 1.0$
- D$9.0 : 1.0$
