Answer:
3 millimeters.
Step-by-step explanation:
There are 10 millimeters in 1 centimeter.
So the answer is 0.3 * 10 = 3 millimeters.
Answer:
Diameter of the cell will be 0.012 mm.
Step-by-step explanation:
The diameter of a white blood cell under magnification was 0.3 centimeters.
Since 1 centimeter = 10 mm
Therefore, 0.3 cm = 0.3×10
= 3 mm
If a microscope has a scale of 250 : 1
Then diameter will be in the same ratio.
[tex]\frac{\text{Diameter of the cell by microscope}}{\text{Original diameter of the cell}}[/tex] = [tex]\frac{250}{1}[/tex]
[tex]\frac{3}{\text{Original diameter of the cell}}[/tex] = [tex]\frac{250}{1}[/tex]
Original diameter of the cell = [tex]\frac{3}{250}[/tex]
= 0.012 mm
