Cumulative Problem 1
A typical human cell is approximately 11 um in diameter and enclosed by a membrane that is 4,4 nm thick. To
simplify the calculations, model the cell as a sphere.
1) What is the volume of the cell? (Express your answer to two significant figures.)

Respuesta :

Answer:

Volume, [tex]V=696.55\ \mu m^3[/tex]

Explanation:

Given that,

The diameter of a human cell is 11 μm

It is enclosed by a membrane that is 4,4 nm thick.

We need to find the volume of the cell. The cell is spherical in shape. The volume of a sphere is given by the formula as follows :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

r is the radius of the sphere, r = 5.5 μm

So,

[tex]V=\dfrac{4}{3}\times 3.14\times (5.5)^3\\\\V=696.55\ \mu m^3[/tex]

So, the volume of the cell is [tex]696.55\ \mu m^3[/tex].
