A scientist prints a micrograph of a fungal cell. The printout includes a scale bar.
The table shows measurements from the printout.
| Feature | Length measured on printout in mm\text{mm}mm | Actual length in μm\mu\text{m}μm |
|---|---|---|
| Scale bar | 24 | 10 |
| Diameter of fungal cell | 72 | not known |
Calculate the magnification of the printed micrograph.
Calculate the actual diameter of the fungal cell in μm\mu\text{m}μm.
