Question 82

50%

In a transmission electron micrograph, a spherical transport vesicle, structure V, has the following measurement:

Real volume = $nm3113,040\text{ nm}^3$

The volume of a sphere is calculated using the equation:

\text{volume} = \frac{4}{3}\pi r^3

where $r$ is the real radius of the sphere.

The diameter of the image of structure V in the micrograph is $mm4.5\text{ mm}$ .

Calculate the magnification of structure V in the micrograph.

Use $π=3.14\pi = 3.14$ .
