Answer: 1014 x 0.01 x 10-6 m = 1 x 106m
Circumference = 2 x 3.14 x 6.38 x 106 = 4.0 x 107 m; No. of times = 40.

Hi,
10^14 cells at 0.01 mm each, lined up, gives a line of
10^14*0.01/1000 m = 10^9 m
Earth's radius is 6.38 x 10^6 m, so
Circumference = 2*PI*6.38 x 10^6 = 40086680 m or so at the equator
then to find how many circumferences in this line of cells,
10^9/40086680 = 25 times or so.
Whether 25 or 40 I would not like to be smeared along the equator
Cheers
