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?

Answer 1

To compare the diameters of the platelet and red blood cell, we need to compute the difference in their sizes.

The diameter of the platelet is 2.33×10^−6 m.
The diameter of the red blood cell is 0.0000075 m.

To find the difference in their sizes, we subtract the diameter of the platelet from the diameter of the red blood cell:

0.0000075 m - 2.33×10^−6 m = 0.000004167 m

Therefore, the red blood cell has a larger diameter than the platelet, and the difference in diameter is approximately 0.000004167 m.
