Platelets and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately 2.33×10^−6 m and 0.0000075 m, respectively. Which blood component has a bigger diameter, and approximately by how much?
To find out which blood component has a bigger diameter and approximately by how much, we can compare the diameters of the platelets and red blood cells.
The diameter of a platelet is approximately 2.33×10^−6 m, which is equivalent to 2.33 micrometers (since 1 micrometer = 10^-6 meters).
The diameter of a red blood cell is approximately 0.0000075 m, which is equivalent to 7.5 micrometers (since 1 micrometer = 10^-6 meters).
Comparing the two, we can see that the diameter of a red blood cell is larger than the diameter of a platelet.
The difference in diameter is approximately 7.5 micrometers - 2.33 micrometers = 5.17 micrometers.
Therefore, the red blood cell has a bigger diameter than the platelet by approximately 5.17 micrometers.
