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.)

Volume,

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 :

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

So,

So, the volume of the cell is .
