Aplant cell has a diameter of 1.3 x 10^-8 kilometer. is it more appropriate to report the diameter of the plant cell as 1.3 x 10^-2 millimeter? explain your reasoning.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
