Question

Based on these examples and your previous calculation of the mean diameter of 10 human cheek cells, determine the volume of an average human cheek cell in mu m^3 assuming that it is a sphere. Human cheek cells are actually flattened and stacked on top of one another in what is called simple squamous epithelium. Assuming that the thickness of an average human cheek cell is 5 mu m, what is the mean volume of an average human check cell in mu m^3? Use the formula for a cylinder. Based on your previous calculation of the mean diameter of 10 human cheek cell nuclei, calculate the average volume of a human check cell nucleus in mu m^3. Assume it is a sphere. If a flattened human check cell (#2) were filled only with nuclei, how many could it hold?

Explanation / Answer

Answer: According to the given informations the required volumes are :

1] here the mean diameter is given = 16.4 cm

and radius = 8.2 cm

Then V = 4/3 * 3.14 * [8.2]3 = 2308.39 cm3

2] here you have given the radius = 8.2 cm = 82000 micro meter

thickness = 5 micro m

Hence the volume = 3.14 * [82000]2 5 = 1.055 * 1011 micro meter3

3] Now again here you need to first write the unit of the radius in micro meter and then using the formula to calculate the desire volume .

I hope you understand it clearlly . Thank you :)
