A typical human red blood cell has a diameter of about 7-8 micrometers, while a human hair ranges from about 17 to 181 micrometers in diameter, depending on the individual and hair type. Therefore, it would take approximately 2 to 25 red blood cells lined up side by side to match the diameter of a single hair.

To estimate how many bacterial cells with a diameter of 2 micrometers (µm) can fit into an epithelial cell with a diameter of 40 µm, we can consider the volumes of the cells. The volume of a sphere is given by ( \frac{4}{3} \pi r^3 ). The radius of the bacterial cell is 1 µm, and the radius of the epithelial cell is 20 µm. Calculating the volumes, the epithelial cell can contain about 400 bacterial cells, assuming they can pack perfectly without any wasted space.

Well, the equation for finding the circumfrence of a circle is (diameter)(pi). That is diameter times pi. since the diameter of a circle is 2 radii, we can say that there is 2(pi) radii in a circle.
22 ft. The diameter is the measurement of a circle through the center from side to side and is equal to two times the radius.
none because........ sorry a hair can have 10000 cells. its amazing how little as a piece of hair have 10000 cells

A human hair has an average diameter of 70 mikrometers and a capillary has an average diameter of 7 mikrometers, so that tells us that 1 hair takes about 10 capillaries in width.

I have the EXACT question on my science homework! I believe it would the suns diameter (1,391,000 kilometers) divided by earths diameter ( 12,757 kilometers) i got 109.03817511954221
Hair has many different things in it. Hair dye, hair spray, gel? Anything you could think of. But hair is made out of dead skin cells and other dead cells. Think of it as "renewable resource".
Two common indirect methods to determine the diameter of a hair in a microscope are by measuring the diameter of the field of view and the number of hairs across the field, and by using a calibration slide with known dimensions for comparison.
The Sun has a diameter of 1,392,684 kilometers. This is equal to 865,374 miles. The Sun is larger than any of the planets.
