The diameter of an average cell in a human body is 1 x 10^-5 mm. If the diameter of a pin head is 2 x 10^-2, how many body cells would fit on the pin head?​

Answer 1

2000

Explanation:

diameter of an average cell= 1 x 10^-5 mm

diameter of a pin head= 2 x 10^-2

number of body cells that would fit on the pin head=2 x 10^-2 ÷ 1 x 10^-5

=2000 body cells
