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?

1 answer

To compare the diameters of the platelet and red blood cell, we need to find the difference between their values.

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, we subtract the diameter of the platelet from the diameter of the red blood cell:

0.0000075 m - 2.33 × 10^(-6) m = 0.00000417 m.

Therefore, the red blood cell has a bigger diameter than the platelet, by approximately 0.00000417 m.
